badblocks: switch to the improved badblock handling code
This patch removes old code of badblocks_set(), badblocks_clear() and badblocks_check(), and make them as wrappers to call _badblocks_set(), _badblocks_clear() and _badblocks_check(). By this change now the badblock handing switch to the improved algorithm in _badblocks_set(), _badblocks_clear() and _badblocks_check(). This patch only contains the changes of old code deletion, new added code for the improved algorithms are in previous patches.

badblocks: improve badblocks_check() for multiple ranges handling
This patch rewrites badblocks_check() with similar coding style as
_badblocks_set() and _badblocks_clear(). The only difference is bad
blocks checking may handle multiple ranges in bad tables now.
If a checking range covers multiple bad blocks range in bad block table,
like the following condition (C is the checking range, E1, E2, E3 are
three bad block ranges in bad block table),
+------------------------------------+
| C |
+------------------------------------+
+----+ +----+ +----+
| E1 | | E2 | | E3 |
+----+ +----+ +----+
The improved badblocks_check() algorithm will divide checking range C
into multiple parts, and handle them in 7 runs of a while-loop,
+--+ +----+ +----+ +----+ +----+ +----+ +----+
|C1| | C2 | | C3 | | C4 | | C5 | | C6 | | C7 |
+--+ +----+ +----+ +----+ +----+ +----+ +----+
+----+ +----+ +----+
| E1 | | E2 | | E3 |
+----+ +----+ +----+
And the start LBA and length of range E1 will be set as first_bad and
bad_sectors for the caller.
The return value rule is consistent for multiple ranges. For example if
there are following bad block ranges in bad block table,
Index No. Start Len Ack
0 400 20 1
1 500 50 1
2 650 20 0
the return value, first_bad, bad_sectors by calling badblocks_set() with
different checking range can be the following values,
Checking Start, Len Return Value first_bad bad_sectors
100, 100 0 N/A N/A
100, 310 1 400 10
100, 440 1 400 10
100, 540 1 400 10
100, 600 -1 400 10
100, 800 -1 400 10
In order to make code review easier, this patch names the improved bad
block range checking routine as _badblocks_check() and does not change
existing badblock_check() code yet. Later patch will delete old code of
badblocks_check() and make it as a wrapper to call _badblocks_check().
Then the new added code won't mess up with the old deleted code, it will
be more clear and easier for code review.

badblocks: improve badblocks_clear() for multiple ranges handling
With the fundamental ideas and helper routines from badblocks_set() improvement, clearing bad block for multiple ranges is much simpler. With a similar idea from badblocks_set() improvement, this patch simplifies bad block range clearing into 5 situations. No matter how complicated the clearing condition is, we just look at the head part of clearing range with relative already set bad block range from the bad block table. The rested part will be handled in next run of the while-loop. Based on existing helpers added from badblocks_set(), this patch adds two more helpers, - front_clear() Clear the bad block range from bad block table which is front overlapped with the clearing range. - front_splitting_clear() Handle the condition that the clearing range hits middle of an already set bad block range from bad block table. Similar as badblocks_set(), the first part of clearing range is handled with relative bad block range which is find by prev_badblocks(). In most cases a valid hint is provided to prev_badblocks() to avoid unnecessary bad block table iteration. This patch also explains the detail algorithm code comments at beginning of badblocks.c, including which five simplified situations are categrized and how all the bad block range clearing conditions are handled by these five situations. Again, in order to make the code review easier and avoid the code changes mixed together, this patch does not modify badblock_clear() and implement another routine called _badblock_clear() for the improvement. Later patch will delete current code of badblock_clear() and make it as a wrapper to _badblock_clear(), so the code change can be much clear for review.

badblocks: improve badblocks_set() for multiple ranges handling
Recently I received a bug report that current badblocks code does not
properly handle multiple ranges. For example,
badblocks_set(bb, 32, 1, true);
badblocks_set(bb, 34, 1, true);
badblocks_set(bb, 36, 1, true);
badblocks_set(bb, 32, 12, true);
Then indeed badblocks_show() reports,
32 3
36 1
But the expected bad blocks table should be,
32 12
Obviously only the first 2 ranges are merged and badblocks_set() returns
and ignores the rest setting range.
This behavior is improper, if the caller of badblocks_set() wants to set
a range of blocks into bad blocks table, all of the blocks in the range
should be handled even the previous part encountering failure.
The desired way to set bad blocks range by badblocks_set() is,
- Set as many as blocks in the setting range into bad blocks table.
- Merge the bad blocks ranges and occupy as less as slots in the bad
blocks table.
- Fast.
Indeed the above proposal is complicated, especially with the following
restrictions,
- The setting bad blocks range can be acknowledged or not acknowledged.
- The bad blocks table size is limited.
- Memory allocation should be avoided.
The basic idea of the patch is to categorize all possible bad blocks
range setting combinations into much less simplified and more less
special conditions. Inside badblocks_set() there is an implicit loop
composed by jumping between labels 're_insert' and 'update_sectors'. No
matter how large the setting bad blocks range is, in every loop just a
minimized range from the head is handled by a pre-defined behavior from
one of the categorized conditions. The logic is simple and code flow is
manageable.
The different relative layout between the setting range and existing bad
block range are checked and handled (merge, combine, overwrite, insert)
by the helpers in previous patch. This patch is to make all the helpers
work together with the above idea.
This patch only has the algorithm improvement for badblocks_set(). There
are following patches contain improvement for badblocks_clear() and
badblocks_check(). But the algorithm in badblocks_set() is fundamental
and typical, other improvement in clear and check routines are based on
all the helpers and ideas in this patch.
In order to make the change to be more clear for code review, this patch
does not directly modify existing badblocks_set(), and just add a new
one named _badblocks_set(). Later patch will remove current existing
badblocks_set() code and make it as a wrapper of _badblocks_set(). So
the new added change won't be mixed with deleted code, the code review
can be easier.

badblocks: add helper routines for badblock ranges handling
This patch adds several helper routines to improve badblock ranges
handling. These helper routines will be used later in the improved
version of badblocks_set()/badblocks_clear()/badblocks_check().
- Helpers prev_by_hint() and prev_badblocks() are used to find the bad
range from bad table which the searching range starts at or after.
- The following helpers are to decide the relative layout between the
manipulating range and existing bad block range from bad table.
- can_merge_behind()
Return 'true' if the manipulating range can backward merge with the
bad block range.
- can_merge_front()
Return 'true' if the manipulating range can forward merge with the
bad block range.
- can_combine_front()
Return 'true' if two adjacent bad block ranges before the
manipulating range can be merged.
- overlap_front()
Return 'true' if the manipulating range exactly overlaps with the
bad block range in front of its range.
- overlap_behind()
Return 'true' if the manipulating range exactly overlaps with the
bad block range behind its range.
- can_front_overwrite()
Return 'true' if the manipulating range can forward overwrite the
bad block range in front of its range.
- The following helpers are to add the manipulating range into the bad
block table. Different routine is called with the specific relative
layout between the manipulating range and other bad block range in the
bad block table.
- behind_merge()
Merge the manipulating range with the bad block range behind its
range, and return the number of merged length in unit of sector.
- front_merge()
Merge the manipulating range with the bad block range in front of
its range, and return the number of merged length in unit of sector.
- front_combine()
Combine the two adjacent bad block ranges before the manipulating
range into a larger one.
- front_overwrite()
Overwrite partial of whole bad block range which is in front of the
manipulating range. The overwrite may split existing bad block range
and generate more bad block ranges into the bad block table.
- insert_at()
Insert the manipulating range at a specific location in the bad
block table.
All the above helpers are used in later patches to improve the bad block
ranges handling for badblocks_set()/badblocks_clear()/badblocks_check().

badblocks: add more helper structure and routines in badblocks.h
This patch adds the following helper structure and routines into badblocks.h, - struct badblocks_context This structure is used in improved badblocks code for bad table iteration. - BB_END() The macro to calculate end LBA of a bad range record from bad table. - badblocks_full() and badblocks_empty() The inline routines to check whether bad table is full or empty. - set_changed() and clear_changed() The inline routines to set and clear 'changed' tag from struct badblocks. These new helper structure and routines can help to make the code more clear, they will be used in the improved badblocks code in following patches.

block/null_blk: add queue_rqs() support
Add batched mq_ops.queue_rqs() support in null_blk for testing. The implementation is much easy since null_blk doesn't have commit_rqs(). We simply handle each request one by one, if errors are encountered, leave them in the passed in list and return back. There is about 3.6% improvement in IOPS of fio/t/io_uring on null_blk with hw_queue_depth=256 on my test VM, from 1.09M to 1.13M.

blk-mq: update driver tags request table when start request
Now we update driver tags request table in blk_mq_get_driver_tag(), so the driver that support queue_rqs() have to update that inflight table by itself. Move it to blk_mq_start_request(), which is a better place where we setup the deadline for request timeout check. And it's just where the request becomes inflight.

blk-mq: account active requests when get driver tag
There is a limit that batched queue_rqs() can't work on shared tags queue, since the account of active requests can't be done there. Now we account the active requests only in blk_mq_get_driver_tag(), which is not the time we get driver tag actually (with none elevator). To support batched queue_rqs() on shared tags queue, we move the account of active requests to where we get the driver tag: 1. none elevator: blk_mq_get_tags() and blk_mq_get_tag() 2. other elevator: __blk_mq_alloc_driver_tag() This is clearer and match with the unaccount side, which just happen when we put the driver tag. The other good point is that we don't need RQF_MQ_INFLIGHT trick anymore, which used to avoid double account of flush request. Now we only account when actually get the driver tag, so all is good. We will remove RQF_MQ_INFLIGHT in the next patch.

x86/purgatory: Remove LTO flags
-flto* implies -ffunction-sections. With LTO enabled, ld.lld generates
multiple .text sections for purgatory.ro:

[19] .text.sha224_fina PROGBITS 0000000000000000 00002cc0
This causes WARNING from kexec_purgatory_setup_sechdrs():
WARNING: CPU: 26 PID: 110894 at kernel/kexec_file.c:919
kexec_load_purgatory+0x37f/0x390
Fix this by disabling LTO for purgatory.
[ AFAICT, x86 is the only arch that supports LTO and purgatory. ]
We could also fix this with an explicit linker script to rejoin .text.*
sections back into .text. However, given the benefit of LTOing purgatory
is small, simply disable the production of more .text.* sections for now.

x86/boot/compressed: Reserve more memory for page tables
The decompressor has a hard limit on the number of page tables it can
allocate. This limit is defined at compile-time and will cause boot
failure if it is reached.
The kernel is very strict and calculates the limit precisely for the
worst-case scenario based on the current configuration. However, it is
easy to forget to adjust the limit when a new use-case arises. The
worst-case scenario is rarely encountered during sanity checks.
In the case of enabling 5-level paging, a use-case was overlooked. The
limit needs to be increased by one to accommodate the additional level.
This oversight went unnoticed until Aaron attempted to run the kernel
via kexec with 5-level paging and unaccepted memory enabled.
Update wost-case calculations to include 5-level paging.
To address this issue, let's allocate some extra space for page tables.
128K should be sufficient for any use-case. The logic can be simplified
by using a single value for all kernel configurations.
[ Also add a warning, should this memory run low - by Dave Hansen. ]

ata: libata-core: fetch sense data for successful commands iff CDL enabled
Currently, we fetch sense data for a _successful_ command if either: 1) Command was NCQ and ATA_DFLAG_CDL_ENABLED flag set (flag ATA_DFLAG_CDL_ENABLED will only be set if the Successful NCQ command sense data supported bit is set); or 2) Command was non-NCQ and regular sense data reporting is enabled. This means that case 2) will trigger for a non-NCQ command which has ATA_SENSE bit set, regardless if CDL is enabled or not. This decision was by design. If the device reports that it has sense data available, it makes sense to fetch that sense data, since the sk/asc/ascq could be important information regardless if CDL is enabled or not. However, the fetching of sense data for a successful command is done via ATA EH. Considering how intricate the ATA EH is, we really do not want to invoke ATA EH unless absolutely needed.

ata: libata-eh: do not clear ATA_PFLAG_EH_PENDING in ata_eh_reset()
ata_scsi_port_error_handler() starts off by clearing ATA_PFLAG_EH_PENDING, before calling ap->ops->error_handler() (without holding the ap->lock). If an error IRQ is received while ap->ops->error_handler() is running, the irq handler will set ATA_PFLAG_EH_PENDING. Once ap->ops->error_handler() returns, ata_scsi_port_error_handler() checks if ATA_PFLAG_EH_PENDING is set, and if it is, another iteration of ATA EH is performed. The problem is that ATA_PFLAG_EH_PENDING is not only cleared by ata_scsi_port_error_handler(), it is also cleared by ata_eh_reset(). ata_eh_reset() is called by ap->ops->error_handler(). This additional clearing done by ata_eh_reset() breaks the whole retry logic in ata_scsi_port_error_handler(). Thus, if an error IRQ is received while ap->ops->error_handler() is running, the port will currently remain frozen and will never get re-enabled. The additional clearing in ata_eh_reset() was introduced in commit |

linux-kselftest-fixes-6.6-rc2
This kselftest fixes update for Linux 6.6-rc2 consists of important
fixes to user_events test and ftrace test.
user_events test has been enabled for default run in Linux 6.6-rc1. The
following fixes are for bugs found since then:
- adds checks for dependencies and skips the test. user_events test
requires root access, and tracefs and user_events enabled. It leaves
tracefs mounted and a fix is in progress for that missing piece.
- creates user_events test-specific Kconfig fragments.
ftrace test fixes:
- unmounts tracefs for recovering environment. Fix identified during the
above mentioned user_events dependencies fix.
- adds softlink to latest log directory improving usage.

Thermal control updates for 6.6-rc2
- Unbreak disabled trip point check in handle_thermal_trip() that may
cause it to skip enabled trip points (Rafael Wysocki).
- Add missing of_node_put() to of_find_trip_id() and
thermal_of_for_each_cooling_maps() that each break out of a
for_each_child_of_node() loop without dropping the reference to
the child object (Julia Lawall).
- Constify the recently added trip argument of the .get_trend() thermal
zone callback (Rafael Wysocki).

dm: don't attempt to queue IO under RCU protection
dm looks up the table for IO based on the request type, with an
assumption that if the request is marked REQ_NOWAIT, it's fine to
attempt to submit that IO while under RCU read lock protection. This
is not OK, as REQ_NOWAIT just means that we should not be sleeping
waiting on other IO, it does not mean that we can't potentially
schedule.
A simple test case demonstrates this quite nicely:
int main(int argc, char *argv[])
{
struct iovec iov;
int fd;
fd = open("/dev/dm-0", O_RDONLY | O_DIRECT);
posix_memalign(&iov.iov_base, 4096, 4096);
iov.iov_len = 4096;
preadv2(fd, &iov, 1, 0, RWF_NOWAIT);
return 0;
}
which will instantly spew:
BUG: sleeping function called from invalid context at include/linux/sched/mm.h:306

where in fact it is dm itself that attempts to allocate a bio clone with
GFP_NOIO under the rcu read lock, regardless of the request type.
Fix this by getting rid of the special casing for REQ_NOWAIT, and just
use the normal SRCU protected table lookup. Get rid of the bio based
table locking helpers at the same time, as they are now unused.
