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. Let it rip!

docs: cdrom: convert docs to ReST and rename to *.rst The stuff there is almost already at ReST format. A conversion for them is trivial: just add a missing titles and fix some scape codes for them to match ReST syntax. While here, rename the cdrom-standard.txt, with was converted from LaTeX to ReST on the previous patch, and add it to the index file. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

[PATCH] cdrom: set default timeout to 7 seconds It's a known fact that Windows times out commands after 7 seconds, so drives generally try and respond if they can before that happens. We default to 5 seconds, which sometimes is a bit too short. Jeremy Higdon reported here: http://lkml.org/lkml/2007/1/1/145 that his drive takes longer than 5 seconds for a "read track information" command, later confirming that it is about 6.7 seconds. So just do the sane thing and change the default command timeout to 7 seconds to avoid other surprises.

block: Switch struct packet_command to use struct scsi_sense_hdr There is a lot of needless struct request_sense usage in the CDROM code. These can all be struct scsi_sense_hdr instead, to avoid any confusion over their respective structure sizes. This patch is a lot of noise changing "sense" to "sshdr", but the final code is more readable to distinguish between "sense" meaning "struct request_sense" and "sshdr" meaning "struct scsi_sense_hdr".

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. Let it rip!

cdrom: Make device operations read-only Since function tables are a common target for attackers, it's best to keep them in read-only memory. As such, this makes the CDROM device ops tables const. This drops additionally n_minors, since it isn't used meaningfully, and sets the only user of cdrom_dummy_generic_packet explicitly so the variables can all be const. Inspired by similar changes in grsecurity/PaX. Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Jens Axboe <axboe@fb.com>

cdrom: don't attempt to fiddle with cdo->capability We can't modify cdo->capability as it is defined as a const. Change the modification hack to just WARN_ON_ONCE() if we hit any of the invalid combinations. This fixes a regression for pcd, which doesn't work after the constify patch.

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.

cdrom: Random writing support for BD-RE media Recently, i bought a blu-ray writer and noticed that while cdrecord worked perfectly, random writing didn't work on rewritable bd-re media. For example, dd if=/dev/zero of=/dev/sr0 bs=32768 count=2 gave the usual "read-only file system" message. After checking if the problem lies with my burner or firmware, i grep-ed the kernel source for EROFS. One of the results was in the cdrom driver. I tried to follow the function chain and ended in the cdrom_is_dvd_rw function where writing is permitted only for DVD-RAM and DVD+RW media. I added a new case label for 0x43 which is the profile name of BD-RE and now it works correctly for BD-RE too. Maybe there is a better way of implementing this, like a new function checking for blu-ray support and called from cdrom_open_write like it happens for mrw and dvdram media, but adding the case label worked. Thank you for your time. Signed-off-by: Jens Axboe <axboe@fb.com>

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.

cdrom: Make device operations read-only Since function tables are a common target for attackers, it's best to keep them in read-only memory. As such, this makes the CDROM device ops tables const. This drops additionally n_minors, since it isn't used meaningfully, and sets the only user of cdrom_dummy_generic_packet explicitly so the variables can all be const.

[PATCH] cdrom: set default timeout to 7 seconds It's a known fact that Windows times out commands after 7 seconds, so drives generally try and respond if they can before that happens. We default to 5 seconds, which sometimes is a bit too short. Jeremy Higdon reported here: http://lkml.org/lkml/2007/1/1/145 that his drive takes longer than 5 seconds for a "read track information" command, later confirming that it is about 6.7 seconds. So just do the sane thing and change the default command timeout to 7 seconds to avoid other surprises.

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.

So we don't need this extra complexitiy in cdrom.c, such as allocating just 8 bytes. The lower layers can handle 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.

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.

treewide: kmalloc() -> kmalloc_array() The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

Hence check whether SCSI passthrough is supported before submitting a SCSI command. Note: both the ide-cd and sr drivers set the disk pointer in struct cdrom_device_info but neither the pcd nor the gdrom driver sets that pointer.

block,scsi: fixup blk_get_request dead queue scenarios The blk_get_request function may fail in low-memory conditions or during device removal (even if __GFP_WAIT is set). To distinguish between these errors, modify the blk_get_request call stack to return the appropriate ERR_PTR. Verify that all callers check the return status and consider IS_ERR instead of a simple NULL pointer check. For consistency, make a similar change to the blk_mq_alloc_request leg of blk_get_request. It may fail if the queue is dead, or the caller was unwilling to wait.

block: introduce struct rq_map_data to use reserved pages This patch introduces struct rq_map_data to enable bio_copy_use_iov() use reserved pages. Currently, bio_copy_user_iov allocates bounce pages but drivers/scsi/sg.c wants to allocate pages by itself and use them. struct rq_map_data can be used to pass allocated pages to bio_copy_user_iov. The current users of bio_copy_user_iov simply passes NULL (they don't want to use pre-allocated pages).

cdrom: move shared static to cdrom_device_info The keeplocked variable in the cdrom driver is shared across multiple drives, but set in per-device ioctls. Move it to the per-device struct, avoiding that the setting on one drive affects the driver's behavior when closing another. [ Impact: limit udev's confusion to one drive when a CD burning program unlocks the CD door at the end of burning. ] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>

cdrom: information leak in cdrom_ioctl_media_changed() This cast is wrong. "cdi->capacity" is an int and "arg" is an unsigned long. The way the check is written now, if one of the high 32 bits is set then we could read outside the info->slots[] array. This bug is pretty old and it predates git.

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!

block: Switch struct packet_command to use struct scsi_sense_hdr There is a lot of needless struct request_sense usage in the CDROM code. These can all be struct scsi_sense_hdr instead, to avoid any confusion over their respective structure sizes. This patch is a lot of noise changing "sense" to "sshdr", but the final code is more readable to distinguish between "sense" meaning "struct request_sense" and "sshdr" meaning "struct scsi_sense_hdr".

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. Let it rip!

drivers/cdrom/cdrom.c: use kzalloc() for failing hardware In drivers/cdrom/cdrom.c mmc_ioctl_cdrom_read_data() allocates a memory area with kmalloc in line 2885. 2885 cgc->buffer = kmalloc(blocksize, GFP_KERNEL); 2886 if (cgc->buffer == NULL) 2887 return -ENOMEM; In line 2908 we can find the copy_to_user function: 2908 if (!ret && copy_to_user(arg, cgc->buffer, blocksize)) The cgc->buffer is never cleaned and initialized before this function. If ret = 0 with the previous basic block, it's possible to display some memory bytes in kernel space from userspace. When we read a block from the disk it normally fills the ->buffer but if the drive is malfunctioning there is a chance that it would only be partially filled. The result is an leak information to userspace.

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.

Use a static atomic to ensure that the function is executed exactly once. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Jens Axboe <axboe@kernel.dk>

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. Let it rip!

[PATCH] sysctl: remove insert_at_head from register_sysctl The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.
