* udf: prevent integer overflow in udf_bitmap_free_blocks()Roman Smirnov2024-06-261-23/+13
| | | | | | | | | | | | | | | An overflow may occur if the function is called with the last block and an offset greater than zero. It is necessary to add a check to avoid this. Found by Linux Verification Center (linuxtesting.org) with Svace. [JK: Make test cover also unalloc table freeing] Link: https://patch.msgid.link/20240620072413.7448-1-r.smirnov@omp.ru Suggested-by: Jan Kara <jack@suse.com> Signed-off-by: Roman Smirnov <r.smirnov@omp.ru> Signed-off-by: Jan Kara <jack@suse.cz>
* udf: Avoid excessive partition lengthsJan Kara2024-06-261-0/+15
| | | | | | | | | | Avoid mounting filesystems where the partition would overflow the 32-bits used for block number. Also refuse to mount filesystems where the partition length is so large we cannot safely index bits in a block bitmap.

* udf: Avoid using corrupted block bitmap bufferJan Kara2024-06-262-3/+15
| | | | | | | | | | | | | | | | When the filesystem block bitmap is corrupted, we detect the corruption while loading the bitmap and fail the allocation with error. However the next allocation from the same bitmap will notice the bitmap buffer is already loaded and tries to allocate from the bitmap with mixed results (depending on the exact nature of the bitmap corruption). Fix the problem by using BH_verified bit to indicate whether the bitmap is valid or not.

* udf: Fix bogus checksum computation in udf_rename()Jan Kara2024-06-201-2/+0
| | | | | | | | | | | | | | | | | | Syzbot reports uninitialized memory access in udf_rename() when updating checksum of '..' directory entry of a moved directory. This is indeed true as we pass on-stack diriter.fi to the udf_update_tag() and because that has only struct fileIdentDesc included in it and not the impUse or name fields, the checksumming function is going to checksum random stack contents beyond the end of the structure. This is actually harmless because the following udf_fiiter_write_fi() will recompute the checksum from on-disk buffers where everything is properly included. So all that is needed is just removing the bogus calculation. Fixes: e9109a92d2a9 ("udf: Convert udf_rename() to new directory iteration code") Link: https://lore.kernel.org/all/000000000000cf405f060d8f75a9@google.com/T/ Link: https://patch.msgid.link/20240617154201.29512-1-jack@suse.cz Reported-by: syzbot+d31185aa54170f7fc1f5@syzkaller.appspotmail.com Signed-off-by: Jan Kara <jack@suse.cz>
* udf: Fix lock ordering in udf_evict_inode()Jan Kara2024-06-052-7/+6
| | | | | | | | | | | | | | | | | | udf_evict_inode() calls udf_setsize() to truncate deleted inode. However inode deletion through udf_evict_inode() can happen from inode reclaim context and udf_setsize() grabs mapping->invalidate_lock which isn't generally safe to acquire from fs reclaim context since we allocate pages under mapping->invalidate_lock for example in a page fault path. This is however not a real deadlock possibility as by the time udf_evict_inode() is called, nobody can be accessing the inode, even less work with its page cache. So this is just a lockdep triggering false positive. Fix the problem by moving mapping->invalidate_lock locking outsize of udf_setsize() into udf_setattr() as grabbing mapping->invalidate_lock from udf_evict_inode() is pointless.

* udf: Drop pointless IS_IMMUTABLE and IS_APPEND checkJan Kara2024-06-051-2/+0
| | | | | | | | | udf_setsize() checks for IS_IMMUTABLE and IS_APPEND flags. This is however pointless as UDF does not have capability to store these flags and never allows to set them. Furthermore this is the only place in UDF code that was actually checking these flags. Remove the pointless check. Signed-off-by: Jan Kara <jack@suse.cz>

| * tracing/selftests: Fix kprobe event name test for .isra. functionsSteven Rostedt (Google)2024-05-291-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kprobe_eventname.tc test checks if a function with .isra. can have a kprobe attached to it. It loops through the kallsyms file for all the functions that have the .isra. name, and checks if it exists in the available_filter_functions file, and if it does, it uses it to attach a kprobe to it. The issue is that kprobes can not attach to functions that are listed more than once in available_filter_functions. With the latest kernel, the function that is found is: rapl_event_update.isra.0 # grep rapl_event_update.isra.0 /sys/kernel/tracing/available_filter_functions rapl_event_update.isra.0 rapl_event_update.isra.0 It is listed twice. This causes the attached kprobe to it to fail which in turn fails the test. Instead of just picking the function function that is found in available_filter_functions, pick the first one that is listed only once in available_filter_functions.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b8b8b4e0c052 ("ata: ahci: Add Intel Alder Lake-P AHCI controller to low power chipsets list") added Intel Alder Lake to the ahci_pci_tbl. Because of the way that the Intel PCS quirk was implemented, having an explicit entry in the ahci_pci_tbl caused the Intel PCS quirk to be applied. (The quirk was not being applied if there was no explict entry.) Thus, entries that were added to the ahci_pci_tbl also got the Intel PCS quirk applied. The quirk was cleaned up in commit 7edbb6059274 ("ahci: clean up intel_pcs_quirk"), such that it is clear which entries that actually applies the Intel PCS quirk. Newer Intel AHCI controllers do not need the Intel PCS quirk, and applying it when not needed actually breaks some platforms. Do not apply the Intel PCS quirk for Intel Alder Lake. This is in line with how things worked before commit b8b8b4e0c052 ("ata: ahci: Add Intel Alder Lake-P AHCI controller to low power chipsets list"), such that certain platforms using Intel Alder Lake will work once again.

If this bit is set by the BIOS then CPUID evaluation including topology enumeration does not work correctly as the evaluation code does not try to analyze any leaf greater than two. This went unnoticed before because the original topology code just repeated evaluation several times and managed to overwrite the initial limited information with the correct one later. The new evaluation code does it once and therefore ends up with the limited and wrong information. Cure this by unlocking CPUID right before evaluating anything which depends on the maximum CPUID leaf being greater than two instead of rereading stuff after unlock.

Fill in a default on those to avoid the problem. Long Story: The kernel dies a horrible death if c->x86_cache_alignment (aka. cache_line_size() is 0. Normally, this value is populated from c->x86_clflush_size. Right now the code is set up to get c->x86_clflush_size from two places. First, modern CPUs get it from CPUID. Old CPUs that don't have leaf 0x80000008 (or CPUID at all) just get some sane defaults from the kernel in get_cpu_address_sizes(). The vast majority of CPUs that have leaf 0x80000008 also get ->x86_clflush_size from CPUID. But there are oddballs. Intel Quark CPUs[1] and others[2] have leaf 0x80000008 but don't set CPUID.01H:EDX[CLFSH], so they skip over filling in ->x86_clflush_size: cpuid(0x00000001, &tfms, &misc, &junk, &cap0); if (cap0 & (1<<19)) c->x86_clflush_size = ((misc >> 8) & 0xff) * 8; So they: land in get_cpu_address_sizes() and see that CPUID has level 0x80000008 and jump into the side of the if() that does not fill in c->x86_clflush_size. That assigns a 0 to c->x86_cache_alignment, and hilarity ensues in code like: buffer = kzalloc(ALIGN(sizeof(*buffer), cache_line_size()), GFP_KERNEL); To fix this, always provide a sane value for ->x86_clflush_size. Big thanks to Andy Shevchenko for finding and reporting this and also providing a first pass at a fix. But his fix was only partial and only worked on the Quark CPUs. It would not, for instance, have worked on the QEMU config. 1. https://raw.githubusercontent.com/InstLatx64/InstLatx64/master/GenuineIntel/GenuineIntel0000590_Clanton_03_CPUID.txt 2. You can also get this behavior if you use "-cpu 486,+clzero" in QEMU.
