While setting prefix path for the root of a cifs_sb, CIFS_MOUNT_USE_PREFIX_PATH flag should also be set. Without it, prepath is not even considered in some places, and output of "mount" and various /proc/<>/*mount* related options can be missing part of the device name.

Currently kdb uses in_interrupt() to determine whether its library code has been called from the kgdb trap handler or from a saner calling context such as driver init. This approach is broken because in_interrupt() alone isn't able to determine kgdb trap handler entry from normal task context. This can happen during normal use of basic features such as breakpoints and can also be trivially reproduced using: echo g > /proc/sysrq-trigger We can improve this by adding check for in_dbg_master() instead which explicitly determines if we are running in debugger context.

This can be found easily by searching for TSHUT. For some reason the thermal shutdown interrupt was never added for 4430, let's add it.

The UVC descriptors report a single supported format and frame size, with bFormatIndex and bFrameIndex both equal to 2, but the video probe and commit controls report bFormatIndex and bFrameIndex set to 1. The device otherwise operates correctly, but the driver rejects the values and fails the format try operation.

To update this array, a new array is allocated, the updates are copied over to the new array, and then the list of functions for the tracepoint is switched over to the new array. After a completion of an RCU grace period, the old array is freed. This process happens for both adding a callback as well as removing one. But on removing a callback, if the new array fails to be allocated, the callback is not removed, and may be used after it is freed by the clients of the tracepoint. There's really no reason to fail if the allocation for a new array fails when removing a function. Instead, the function can simply be replaced by a stub function that could be cleaned up on the next modification of the array. That is, instead of calling the function registered to the tracepoint, it would call a stub function in its place.

Static calls do the same thing, so this trick is not without precedent. There's another solution that uses RCU tricks and is more complex, but can be an alternative if this solution becomes an issue.

When the status is -2 (busy, call again), we call ibm,configure-connector again immediately without checking whether to schedule, which can result in monopolizing the CPU. 2. Extended delay status (9900..9905) goes completely unhandled, causing the configuration to unnecessarily terminate. Fix both of these issues by using rtas_busy_delay().

After commit 77b425399f6d ("Input: i8042 - use chassis info to skip selftest on Asus laptops"), all modern Asus laptops have the i8042 selftest disabled. It has done by using chassys type "10" (laptop). The Asus Zenbook Flip suffers from similar suspend/resume issues, but it _sometimes_ work and sometimes it doesn't. Setting noselftest makes it work reliably. In this case, we need to add chassis type "31" (convertible) in order to avoid selftest in this device.

When recovering a relocation, if we run into a reloc root that has 0 refs we simply add it to the reloc_control->reloc_roots list, and then clean it up later. The problem with this is __del_reloc_root() doesn't do anything if the root isn't in the radix tree, which in this case it won't be because we never call __add_reloc_root() on the reloc_root. This exit condition simply isn't correct really. During normal operation we can remove ourselves from the rb tree and then we're meant to clean up later at merge_reloc_roots() time, and this happens correctly. During recovery we're depending on free_reloc_roots() to drop our references, but we're short-circuiting. Fix this by continuing to check if we're on the list and dropping ourselves from the reloc_control root list and dropping our reference appropriately. Change the corresponding BUG_ON() to an ASSERT() that does the correct thing if we aren't in the rb tree.

Force all CPUs to do VMXOFF (via NMI shootdown) during an emergency reboot if VMX is _supported_, as VMX being off on the current CPU does not prevent other CPUs from being in VMX root (post-VMXON). This fixes a bug where a crash/panic reboot could leave other CPUs in VMX root and prevent them from being woken via INIT-SIPI-SIPI in the new kernel.

This issue was originally fixed in 09954bad4 ("floppy: refactor open() flags handling"). The fix as a side-effect, however, introduce issue for open(O_ACCMODE) that is being used for ioctl-only open. I wrote a fix for that, but instead of it being merged, full revert of 09954bad4 was performed, re-introducing the O_NDELAY / O_NONBLOCK issue, and it strikes again. This is a forward-port of the original fix to current codebase; the original submission had the changelog below: ==== Commit 09954bad4 ("floppy: refactor open() flags handling"), as a side-effect, causes open(/dev/fdX, O_ACCMODE) to fail. It turns out that this is being used setfdprm userspace for ioctl-only open(). Reintroduce back the original behavior wrt !(FMODE_READ|FMODE_WRITE) modes, while still keeping the original O_NDELAY bug fixed.

The two forms should have identical behaviors on x86-64 but the former causes GNU as<2.37 to produce an unreferenced undefined symbol _GLOBAL_OFFSET_TABLE_. (On x86-32, there is an R_386_PC32 vs R_386_PLT32 difference but the linker behavior is identical as far as Linux kernel is concerned.) Simply ignore _GLOBAL_OFFSET_TABLE_ for now, like what scripts/mod/modpost.c:ignore_undef_symbol does. This also fixes the problem for gcc/clang -fpie and -fpic, which may emit `call foo@PLT` for external function calls on x86. Note: ld -z defs and dynamic loaders do not error for unreferenced undefined symbols so the module loader is reading too much. If we ever need to ignore more symbols, the code should be refactored to ignore unreferenced symbols.

Back in 2.1.29 the clear_user() guts (__bzero()) had been merged with memset(). Unfortunately, while all exception handlers had been copied, one of the exception table entries got lost. As the result, clear_user() starting at 128*n bytes before the end of page and spanning between 8 and 127 bytes into the next page would oops when the second page is unmapped. It's trivial to reproduce - all it takes is main() { int fd = open("/dev/zero", O_RDONLY); char *p = mmap(NULL, 16384, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANON, -1, 0); munmap(p + 8192, 8192); read(fd, p + 8192 - 128, 192); } which had been oopsing since March 1997. Says something about the quality of test coverage... ;-/ And while today sparc32 port is nearly dead, back in '97 it had been very much alive; in fact, sparc64 had only been in mainline for 3 months by that point...

Following a system crash, dm-era fails to recover the committed writeset for the current era, leading to lost writes. That is, we lose the information about what blocks were written during the affected era. dm-era assumes that the writeset of the current era is archived when the device is suspended. So, when resuming the device, it just moves on to the next era, ignoring the committed writeset. This assumption holds when the device is properly shut down. But, when the system crashes, the code that suspends the target never runs, so the writeset for the current era is not archived. There are three issues that cause the committed writeset to get lost: 1. dm-era doesn't load the committed writeset when opening the metadata 2. The code that resizes the metadata wipes the information about the committed writeset (assuming it was loaded at step 1) 3. era_preresume() starts a new era, without taking into account that the current era might not have been archived, due to a system crash. To fix this: 1. Load the committed writeset when opening the metadata 2. Fix the code that resizes the metadata to make sure it doesn't wipe the loaded writeset 3. Fix era_preresume() to check for a loaded writeset and archive it, before starting a new era.

In case of devices with at most 64 blocks, the digestion of consecutive eras uses the writeset of the first era as the writeset of all eras to digest, leading to lost writes. That is, we lose the information about what blocks were written during the affected eras. The digestion code uses a dm_disk_bitset object to access the archived writesets. This structure includes a one word (64-bit) cache to reduce the number of array lookups. This structure is initialized only once, in metadata_digest_start(), when we kick off digestion. But, when we insert a new writeset into the writeset tree, before the digestion of the previous writeset is done, or equivalently when there are multiple writesets in the writeset tree to digest, then all these writesets are digested using the same cache and the cache is not re-initialized when moving from one writeset to the next. For devices with more than 64 blocks, i.e., the size of the cache, the cache is indirectly invalidated when we move to a next set of blocks, so we avoid the bug. But for devices with at most 64 blocks we end up using the same cached data for digesting all archived writesets, i.e., the cache is loaded when digesting the first writeset and it never gets reloaded, until the digestion is done. As a result, the writeset of the first era to digest is used as the writeset of all the following archived eras, leading to lost writes. Fix this by reinitializing the dm_disk_bitset structure, and thus invalidating the cache, every time the digestion code starts digesting a new writeset.

Metadata resize shouldn't happen in the ctr. The ctr loads a temporary (inactive) table that will only become active upon resume. That is why resize should always be done in terms of resume. Otherwise a load (ctr) whose inactive table never becomes active will incorrectly resize the metadata. Also, perform the resize directly in preresume, instead of using the worker to do it. The worker might run other metadata operations, e.g., it could start digestion, before resizing the metadata. These operations will end up using the old size. This could lead to errors, like: device-mapper: era: metadata_digest_transcribe_writeset: dm_array_set_value failed device-mapper: era: process_old_eras: digest step failed, stopping digestion The reason of the above error is that the worker started the digestion of the archived writeset using the old, larger size. As a result, metadata_digest_transcribe_writeset tried to write beyond the end of the era array.

Donenfeld commit 0b41713b606694257b90d61ba7e2712d8457648b upstream. This introduces a helper function to be called only by network drivers that wraps calls to icmp[v6]_send in a conntrack transformation, in case NAT has been used. We don't want to pollute the non-driver path, though, so we introduce this as a helper to be called by places that actually make use of this, as suggested by Florian. Signed-off-by: Jason A.

Donenfeld commit 67c9a7e1e3ac491b5df018803639addc36f154ba upstream. Because sunvnet is calling icmp from network device context, it should use the ndo helper so that the rate limiting applies correctly. While we're at it, doing the additional route lookup before calling icmp_ndo_send is superfluous, since this is the job of the icmp code in the first place. Signed-off-by: Jason A.

Donenfeld commit ee576c47db60432c37e54b1e2b43a8ca6d3a8dca upstream. The icmp{,v6}_send functions make all sorts of use of skb->cb, casting it with IPCB or IP6CB, assuming the skb to have come directly from the inet layer. But when the packet comes from the ndo layer, especially when forwarded, there's no telling what might be in skb->cb at that point. As a result, the icmp sending code risks reading bogus memory contents, which can result in nasty stack overflows such as this one reported by a user: panic+0x108/0x2ea __stack_chk_fail+0x14/0x20 __icmp_send+0x5bd/0x5c0 icmp_ndo_send+0x148/0x160 In icmp_send, skb->cb is cast with IPCB and an ip_options struct is read from it. The optlen parameter there is of particular note, as it can induce writes beyond bounds. There are quite a few ways that can happen in __ip_options_echo. For example: // sptr/skb are attacker-controlled skb bytes sptr = skb_network_header(skb); // dptr/dopt points to stack memory allocated by __icmp_send dptr = dopt->__data; // sopt is the corrupt skb->cb in question if (sopt->rr) { optlen = sptr[sopt->rr+1]; // corrupt skb->cb + skb->data soffset = sptr[sopt->rr+2]; // corrupt skb->cb + skb->data // this now writes potentially attacker-controlled data, over // flowing the stack: memcpy(dptr, sptr+sopt->rr, optlen); } In the icmpv6_send case, the story is similar, but not as dire, as only IP6CB(skb)->iif and IP6CB(skb)->dsthao are used. The dsthao case is worse than the iif case, but it is passed to ipv6_find_tlv, which does a bit of bounds checking on the value. This is easy to simulate by doing a `memset(skb->cb, 0x41, sizeof(skb->cb));` before calling icmp{,v6}_ndo_send, and it's only by good fortune and the rarity of icmp sending from that context that we've avoided reports like this until now. For example, in KASAN: BUG: KASAN: stack-out-of-bounds in __ip_options_echo+0xa0e/0x12b0 Write of size 38 at addr ffff888006f1f80e by task ping/89 CPU: 2 PID: 89 Comm: ping Not tainted 5.10.0-rc7-debug+ #5 Call Trace: dump_stack+0x9a/0xcc print_address_description.constprop.0+0x1a/0x160 __kasan_report.cold+0x20/0x38 kasan_report+0x32/0x40 check_memory_region+0x145/0x1a0 memcpy+0x39/0x60 __ip_options_echo+0xa0e/0x12b0 __icmp_send+0x744/0x1700 Actually, out of the 4 drivers that do this, only gtp zeroed the cb for the v4 case, while the rest did not. So this commit actually removes the gtp-specific zeroing, while putting the code where it belongs in the shared infrastructure of icmp{,v6}_ndo_send. This commit fixes the issue by passing an empty IPCB or IP6CB along to the functions that actually do the work. For the icmp_send, this was already trivial, thanks to __icmp_send providing the plumbing function. For icmpv6_send, this required a tiny bit of refactoring to make it behave like the v4 case, after which it was straight forward.
