License cleanup: add SPDX GPL-2.0 license identifier to files with no license Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

[NET]: Make /proc/net per network namespace This patch makes /proc/net per network namespace. It modifies the global variables proc_net and proc_net_stat to be per network namespace. The proc_net file helpers are modified to take a network namespace argument, and all of their callers are fixed to pass &init_net for that argument. This ensures that all of the /proc/net files are only visible and usable in the initial network namespace until the code behind them has been updated to be handle multiple network namespaces. Making /proc/net per namespace is necessary as at least some files in /proc/net depend upon the set of network devices which is per network namespace, and even more files in /proc/net have contents that are relevant to a single network namespace.

net: break include loop netdevice.h, dsa.h, devlink.h There is an include loop between netdevice.h, dsa.h, devlink.h because of NETDEV_ALIGN, making it impossible to use devlink structures in dsa.h. Break this loop by taking dsa.h out of netdevice.h, add a forward declaration of dsa_switch_tree and netdev_set_default_ethtool_ops() function, which is what netdevice.h requires. No longer having dsa.h in netdevice.h means the includes in dsa.h no longer get included. This breaks a few other files which depend on these includes. Add these directly in the affected file.

ipconfig: send Client-identifier in DHCP requests A dhcp server may provide parameters to a client from a pool of IP addresses and using a shared rootfs, or provide a specific set of parameters for a specific client, usually using the MAC address to identify each client individually. The dhcp protocol also specifies a client-id field which can be used to determine the correct parameters to supply when no MAC address is available. There is currently no way to tell the kernel to supply a specific client-id, only the userspace dhcp clients support this feature, but this can not be used when the network is needed before userspace is available such as when the root filesystem is on NFS. This patch is to be able to do something like "ip=dhcp,client_id_type, client_id_value", as a kernel parameter to enable the kernel to identify itself to the server.

ipv4: ipconfig: avoid unused ic_proto_used symbol When CONFIG_PROC_FS, CONFIG_IP_PNP_BOOTP, CONFIG_IP_PNP_DHCP and CONFIG_IP_PNP_RARP are all disabled, we get a warning about the ic_proto_used variable being unused: net/ipv4/ipconfig.c:146:12: error: 'ic_proto_used' defined but not used [-Werror=unused-variable] This avoids the warning, by making the definition conditional on whether a dynamic IP configuration protocol is configured. If not, we know that the value is always zero, so we can optimize away the variable and all code that depends on it. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S.

ipv4: teach ipconfig about the MTU option in DHCP The DHCP spec allows the server to specify the MTU. This can be useful for netbooting with UDP-based NFS-root on a network using jumbo frames. This patch allows the kernel IP autoconfiguration to handle this option correctly. It would be possible to use initramfs and add a script to set the MTU, but that seems like a complicated solution if no initramfs is otherwise necessary, and would bloat the kernel image more than this code would.

net: ipconfig: Support using "delayed" DHCP replies The dhcp code only waits 1s between sending DHCP requests on different devices and only accepts an answer for the device that sent out the last request. Only the timeout at the end of a loop is increased iteratively which favours only the last device. This makes it impossible to work with a dhcp server that takes little more than 1s connected to a device that is not the last one. Instead of also increasing the inter-device timeout, teach the code to handle delayed replies. To accomplish that, make *ic_dev track the current ic_device instead of the current net_device and adapt all users accordingly. The relevant change then is to reset d to ic_dev on a reply to assert that the followup request goes through the right device.

ipconfig: add informative timeout messages while waiting for carrier Commit 3fb72f1e6e6165c5f495e8dc11c5bbd14c73385c ("ipconfig wait for carrier") added a "wait for carrier on at least one interface" policy, with a worst case maximum wait of two minutes. However, if you encounter this, you won't get any feedback from the console as to the nature of what is going on. You just see the booting process hang for two minutes and then continue. Here we add a message so the user knows what is going on, and hence can take action to rectify the situation (e.g. fix network cable or whatever.) After the 1st 10s pause, output now begins that looks like this: Waiting up to 110 more seconds for network. Waiting up to 100 more seconds for network. Waiting up to 90 more seconds for network. Waiting up to 80 more seconds for network. ... Since most systems will have no problem getting link/carrier in the 1st 10s, the only people who will see these messages are people with genuine issues that need to be resolved.

net: ipv4: handle DSA enabled master network devices The logic to configure a network interface for kernel IP auto-configuration is very simplistic, and does not handle the case where a device is stacked onto another such as with DSA. This causes the kernel not to open and configure the master network device in a DSA switch tree, and therefore slave network devices using this master network devices as conduit device cannot be open. This restriction comes from a check in net/dsa/slave.c, which is basically checking the master netdev flags for IFF_UP and returns -ENETDOWN if it is not the case. Automatically bringing-up DSA master network devices allows DSA slave network devices to be used as valid interfaces for e.g: NFS root booting by allowing kernel IP autoconfiguration to succeed on these interfaces. On the reverse path, make sure we do not attempt to close a DSA-enabled device as this would implicitely prevent the slave DSA network device from operating.

[NET]: Make the device list and device lookups per namespace. This patch makes most of the generic device layer network namespace safe. This patch makes dev_base_head a network namespace variable, and then it picks up a few associated variables. The functions: dev_getbyhwaddr dev_getfirsthwbytype dev_get_by_flags dev_get_by_name __dev_get_by_name dev_get_by_index __dev_get_by_index dev_ioctl dev_ethtool dev_load wireless_process_ioctl were modified to take a network namespace argument, and deal with it. vlan_ioctl_set and brioctl_set were modified so their hooks will receive a network namespace argument. So basically anthing in the core of the network stack that was affected to by the change of dev_base was modified to handle multiple network namespaces. The rest of the network stack was simply modified to explicitly use &init_net the initial network namespace. This can be fixed when those components of the network stack are modified to handle multiple network namespaces. For now the ifindex generator is left global. Fundametally ifindex numbers are per namespace, or else we will have corner case problems with migration when we get that far. At the same time there are assumptions in the network stack that the ifindex of a network device won't change. Making the ifindex number global seems a good compromise until the network stack can cope with ifindex changes when you change namespaces, and the like. Signed-off-by: Eric W.

net: have ipconfig not wait if no dev is available previous commit 3fb72f1e6e6165c5f495e8dc11c5bbd14c73385c makes IP-Config wait for carrier on at least one network device. Before waiting (predefined value 120s), check that at least one device was successfully brought up. Otherwise (e.g. buggy bootloader which does not set the MAC address) there is no point in waiting for carrier.

ipconfig: add informative timeout messages while waiting for carrier Commit 3fb72f1e6e6165c5f495e8dc11c5bbd14c73385c ("ipconfig wait for carrier") added a "wait for carrier on at least one interface" policy, with a worst case maximum wait of two minutes. However, if you encounter this, you won't get any feedback from the console as to the nature of what is going on. You just see the booting process hang for two minutes and then continue. Here we add a message so the user knows what is going on, and hence can take action to rectify the situation (e.g. fix network cable or whatever.) After the 1st 10s pause, output now begins that looks like this: Waiting up to 110 more seconds for network. Waiting up to 100 more seconds for network. Waiting up to 90 more seconds for network. Waiting up to 80 more seconds for network. ... Since most systems will have no problem getting link/carrier in the 1st 10s, the only people who will see these messages are people with genuine issues that need to be resolved.

ipconfig: Handle devices which take some time to come up. Some network devices, particularly USB ones, take several seconds to fully init and appear in the device list. If the user turned ipconfig on, they are using it for NFS root or some other early booting purpose. So it makes no sense to just flat out fail immediately if the device isn't found. It also doesn't make sense to just jack up the initial wait to something crazy like 10 seconds. Instead, poll immediately, and then periodically once a second, waiting for a usable device to appear. Fail after 12 seconds. Signed-off-by: David S. Miller <davem@davemloft.net> Tested-by: Christian Pellegrin <chripell@fsfe.org>

net: ipconfig: fix ic_close_devs() use-after-free Our chosen ic_dev may be anywhere in our list of ic_devs, and we may free it before attempting to close others. When we compare d->dev and ic_dev->dev, we're potentially dereferencing memory returned to the allocator. This causes KASAN to scream for each subsequent ic_dev we check. As there's a 1-1 mapping between ic_devs and netdevs, we can instead compare d and ic_dev directly, which implicitly handles the !ic_dev case, and avoids the use-after-free. The ic_dev pointer may be stale, but we will not dereference it.

ipv4: teach ipconfig about the MTU option in DHCP The DHCP spec allows the server to specify the MTU. This can be useful for netbooting with UDP-based NFS-root on a network using jumbo frames. This patch allows the kernel IP autoconfiguration to handle this option correctly. It would be possible to use initramfs and add a script to set the MTU, but that seems like a complicated solution if no initramfs is otherwise necessary, and would bloat the kernel image more than this code would.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

net: ipconfig: Support using "delayed" DHCP replies The dhcp code only waits 1s between sending DHCP requests on different devices and only accepts an answer for the device that sent out the last request. Only the timeout at the end of a loop is increased iteratively which favours only the last device. This makes it impossible to work with a dhcp server that takes little more than 1s connected to a device that is not the last one. Instead of also increasing the inter-device timeout, teach the code to handle delayed replies. To accomplish that, make *ic_dev track the current ic_device instead of the current net_device and adapt all users accordingly. The relevant change then is to reset d to ic_dev on a reply to assert that the followup request goes through the right device.

ipv4: teach ipconfig about the MTU option in DHCP The DHCP spec allows the server to specify the MTU. This can be useful for netbooting with UDP-based NFS-root on a network using jumbo frames. This patch allows the kernel IP autoconfiguration to handle this option correctly. It would be possible to use initramfs and add a script to set the MTU, but that seems like a complicated solution if no initramfs is otherwise necessary, and would bloat the kernel image more than this code would.

net: ipconfig: Support using "delayed" DHCP replies The dhcp code only waits 1s between sending DHCP requests on different devices and only accepts an answer for the device that sent out the last request. Only the timeout at the end of a loop is increased iteratively which favours only the last device. This makes it impossible to work with a dhcp server that takes little more than 1s connected to a device that is not the last one. Instead of also increasing the inter-device timeout, teach the code to handle delayed replies. To accomplish that, make *ic_dev track the current ic_device instead of the current net_device and adapt all users accordingly. The relevant change then is to reset d to ic_dev on a reply to assert that the followup request goes through the right device.

ipv4: teach ipconfig about the MTU option in DHCP The DHCP spec allows the server to specify the MTU. This can be useful for netbooting with UDP-based NFS-root on a network using jumbo frames. This patch allows the kernel IP autoconfiguration to handle this option correctly. It would be possible to use initramfs and add a script to set the MTU, but that seems like a complicated solution if no initramfs is otherwise necessary, and would bloat the kernel image more than this code would.

ipconfig: send Client-identifier in DHCP requests A dhcp server may provide parameters to a client from a pool of IP addresses and using a shared rootfs, or provide a specific set of parameters for a specific client, usually using the MAC address to identify each client individually. The dhcp protocol also specifies a client-id field which can be used to determine the correct parameters to supply when no MAC address is available. There is currently no way to tell the kernel to supply a specific client-id, only the userspace dhcp clients support this feature, but this can not be used when the network is needed before userspace is available such as when the root filesystem is on NFS. This patch is to be able to do something like "ip=dhcp,client_id_type, client_id_value", as a kernel parameter to enable the kernel to identify itself to the server.

This also fixes the problem with needed_headroom changing between allocating the skb and reserving the head room. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

[IPCONFIG]: The kernel gets no IP from some DHCP servers From: Stephen Hemminger <shemminger@linux-foundation.org> Based upon a patch by Marcel Wappler: This patch fixes a DHCP issue of the kernel: some DHCP servers (i.e. in the Linksys WRT54Gv5) are very strict about the contents of the DHCPDISCOVER packet they receive from clients. Table 5 in RFC2131 page 36 requests the fields 'ciaddr' and 'siaddr' MUST be set to '0'. These DHCP servers ignore Linux kernel's DHCP discovery packets with these two fields set to '255.255.255.255' (in contrast to popular DHCP clients, such as 'dhclient' or 'udhcpc'). This leads to a not booting system. Signed-off-by: David S. Miller <davem@davemloft.net>

net: ipconfig: Support using "delayed" DHCP replies The dhcp code only waits 1s between sending DHCP requests on different devices and only accepts an answer for the device that sent out the last request. Only the timeout at the end of a loop is increased iteratively which favours only the last device. This makes it impossible to work with a dhcp server that takes little more than 1s connected to a device that is not the last one. Instead of also increasing the inter-device timeout, teach the code to handle delayed replies. To accomplish that, make *ic_dev track the current ic_device instead of the current net_device and adapt all users accordingly. The relevant change then is to reset d to ic_dev on a reply to assert that the followup request goes through the right device.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

net: ipconfig: Support using "delayed" DHCP replies The dhcp code only waits 1s between sending DHCP requests on different devices and only accepts an answer for the device that sent out the last request. Only the timeout at the end of a loop is increased iteratively which favours only the last device. This makes it impossible to work with a dhcp server that takes little more than 1s connected to a device that is not the last one. Instead of also increasing the inter-device timeout, teach the code to handle delayed replies. To accomplish that, make *ic_dev track the current ic_device instead of the current net_device and adapt all users accordingly. The relevant change then is to reset d to ic_dev on a reply to assert that the followup request goes through the right device.

[IPV4]: ipconfig.c: fix dhcp timeout behaviour I think there is a small bug in ipconfig.c in case IPCONFIG_DHCP is set and dhcp is used. When a DHCPOFFER is received, ip address is kept until we get DHCPACK. If no ack is received, ic_dynamic() returns negatively, but leaves the offered ip address in ic_myaddr. This makes the main loop in ip_auto_config() break and uses the maybe incomplete configuration. Not sure if it's the best way to do, but the following trivial patch correct this.

ipconfig: Handle devices which take some time to come up. Some network devices, particularly USB ones, take several seconds to fully init and appear in the device list. If the user turned ipconfig on, they are using it for NFS root or some other early booting purpose. So it makes no sense to just flat out fail immediately if the device isn't found. It also doesn't make sense to just jack up the initial wait to something crazy like 10 seconds. Instead, poll immediately, and then periodically once a second, waiting for a usable device to appear. Fail after 12 seconds. Signed-off-by: David S. Miller <davem@davemloft.net> Tested-by: Christian Pellegrin <chripell@fsfe.org>

ipconfig wait for carrier v3 -> v4: fix return boolean false instead of 0 for ic_is_init_dev Currently the ip auto configuration has a hardcoded delay of 1 second. When (ethernet) link takes longer to come up (e.g. more than 3 seconds), nfs root may not be found. Remove the hardcoded delay, and wait for carrier on at least one network device.

ipconfig: add nameserver IPs to kernel-parameter ip= On small systems (e.g. embedded ones) IP addresses are often configured by bootloaders and get assigned to kernel via parameter "ip=". If set to "ip=dhcp", even nameserver entries from DHCP daemons are handled. These entries exported in /proc/net/pnp are commonly linked by /etc/resolv.conf. To configure nameservers for networks without DHCP, this patch adds option <dns0-ip> and <dns1-ip> to kernel-parameter 'ip='.

net: ipconfig: Support using "delayed" DHCP replies The dhcp code only waits 1s between sending DHCP requests on different devices and only accepts an answer for the device that sent out the last request. Only the timeout at the end of a loop is increased iteratively which favours only the last device. This makes it impossible to work with a dhcp server that takes little more than 1s connected to a device that is not the last one. Instead of also increasing the inter-device timeout, teach the code to handle delayed replies. To accomplish that, make *ic_dev track the current ic_device instead of the current net_device and adapt all users accordingly. The relevant change then is to reset d to ic_dev on a reply to assert that the followup request goes through the right device.

ipv4: teach ipconfig about the MTU option in DHCP The DHCP spec allows the server to specify the MTU. This can be useful for netbooting with UDP-based NFS-root on a network using jumbo frames. This patch allows the kernel IP autoconfiguration to handle this option correctly. It would be possible to use initramfs and add a script to set the MTU, but that seems like a complicated solution if no initramfs is otherwise necessary, and would bloat the kernel image more than this code would.

ipconfig: send Client-identifier in DHCP requests A dhcp server may provide parameters to a client from a pool of IP addresses and using a shared rootfs, or provide a specific set of parameters for a specific client, usually using the MAC address to identify each client individually. The dhcp protocol also specifies a client-id field which can be used to determine the correct parameters to supply when no MAC address is available. There is currently no way to tell the kernel to supply a specific client-id, only the userspace dhcp clients support this feature, but this can not be used when the network is needed before userspace is available such as when the root filesystem is on NFS. This patch is to be able to do something like "ip=dhcp,client_id_type, client_id_value", as a kernel parameter to enable the kernel to identify itself to the server.

[IPV4] Fix ip=dhcp regression David Brownell pointed out a regression in my recent "Fix ip command line processing" patch. It turns out to be a fairly blatant oversight on my part whereby ic_enable is never set, and thus autoconfiguration is never enabled. Clearly my testing was broken :-( The solution that I have is to set ic_enable to 1 if we hit ip_auto_config_setup(), which basically means that autoconfiguration is activated unless told otherwise. I then flip ic_enable to 0 if ip=off, ip=none, ip=::::::off or ip=::::::none using ic_proto_name(); The incremental patch is below, let me know if a non-incremental version is prepared, as I did as for the original patch to be reverted pending a fix.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] namespaces: utsname: switch to using uts namespaces Replace references to system_utsname to the per-process uts namespace where appropriate. This includes things like uname. Changes: Per Eric Biederman's comments, use the per-process uts namespace for ELF_PLATFORM, sunrpc, and parts of net/ipv4/ipconfig.c [jdike@addtoit.com: UML fix] [clg@fr.ibm.com: cleanup] [akpm@osdl.org: build fix] Signed-off-by: Serge E.

[IPV4] ipconfig: Fix regression in ip command line processing The recent changes for ip command line processing fixed some problems but unfortunately broke some common usage scenarios. In current 2.6.24-rc6 the following command line results in no IP address assignment, which is surely a regression: ip=10.0.2.15::10.0.2.2:255.255.255.0::eth0:off Please find below a patch that works for all cases I can find.

ipconfig: add nameserver IPs to kernel-parameter ip= On small systems (e.g. embedded ones) IP addresses are often configured by bootloaders and get assigned to kernel via parameter "ip=". If set to "ip=dhcp", even nameserver entries from DHCP daemons are handled. These entries exported in /proc/net/pnp are commonly linked by /etc/resolv.conf. To configure nameservers for networks without DHCP, this patch adds option <dns0-ip> and <dns1-ip> to kernel-parameter 'ip='.

net: Convert printks to pr_<level> Use a more current kernel messaging style. Convert a printk block to print_hex_dump. Coalesce formats, align arguments. Use %s, __func__ instead of embedding function names. Some messages that were prefixed with <foo>_close are now prefixed with <foo>_fini. Some ah4 and esp messages are now not prefixed with "ip ". The intent of this patch is to later add something like #define pr_fmt(fmt) "IPv4: " fmt. to standardize the output messages. Text size is trivially reduced.
