There are many same functions like _rtl88e_phy_calculate_bit_shift(), _rtl92c_phy_calculate_bit_shift() and so on. And these functions can cause undefined bitwise shift behavior. Add calculate_bit_shift() to replace them and fix undefined behavior in subsequent patches.

2023-12-21keys, dns: Allow key types (eg. DNS) to be reclaimed immediately on expiryDavid Howells6-23/+47
If a key has an expiration time, then when that time passes, the key is left around for a certain amount of time before being collected (5 mins by default) so that EKEYEXPIRED can be returned instead of ENOKEY. This is a problem for DNS keys because we want to redo the DNS lookup immediately at that point. Fix this by allowing key types to be marked such that keys of that type don't have this extra period, but are reclaimed as soon as they expire and turn this on for dns_resolver-type keys. To make this easier to handle, key->expiry is changed to be permanent if TIME64_MAX rather than 0. Furthermore, give such new-style negative DNS results a 1s default expiry if no other expiry time is set rather than allowing it to stick around indefinitely. This shouldn't be zero as ls will follow a failing stat call immediately with a second with AT_SYMLINK_NOFOLLOW added.

2023-12-21bpf: Re-support uid and gid when mounting bpffsDaniel Borkmann1-2/+51
For a clean, conflict-free revert of the token-related patches in commit d17aff807f84 ("Revert BPF token-related functionality"), the bpf fs commit 750e785796bb ("bpf: Support uid and gid when mounting bpffs") was undone temporarily as well. This patch manually re-adds the functionality from the original one back in 750e785796bb, no other functional changes intended. Testing: # mount -t bpf -o uid=65534,gid=65534 bpffs ./foo # ls -la . | grep foo drwxrwxrwt 2 nobody nogroup 0 Dec 20 13:16 foo # mount -t bpf bpffs on /root/foo type bpf (rw,relatime,uid=65534,gid=65534) Also, passing invalid arguments for uid/gid are properly rejected as expected.

2023-12-21gpio: dwapb: mask/unmask IRQ when disable/enale itxiongxin1-4/+8
In the hardware implementation of the I2C HID driver based on DesignWare GPIO IRQ chip, when the user continues to use the I2C HID device in the suspend process, the I2C HID interrupt will be masked after the resume process is finished. This is because the disable_irq()/enable_irq() of the DesignWare GPIO driver does not synchronize the IRQ mask register state. In normal use of the I2C HID procedure, the GPIO IRQ irq_mask()/irq_unmask() functions are called in pairs. In case of an exception, i2c_hid_core_suspend() calls disable_irq() to disable the GPIO IRQ. With low probability, this causes irq_unmask() to not be called, which causes the GPIO IRQ to be masked and not unmasked in enable_irq(), raising an exception. Add synchronization to the masked register state in the dwapb_irq_enable()/dwapb_irq_disable() function. mask the GPIO IRQ before disabling it. After enabling the GPIO IRQ, unmask the IRQ.

2023-12-21net: check dev->gso_max_size in gso_features_check()Eric Dumazet1-0/+3
Some drivers might misbehave if TSO packets get too big. GVE for instance uses a 16bit field in its TX descriptor, and will do bad things if a packet is bigger than 2^16 bytes. Linux TCP stack honors dev->gso_max_size, but there are other ways for too big packets to reach an ndo_start_xmit() handler : virtio_net, af_packet, GRO... Add a generic check in gso_features_check() and fallback to GSO when needed. gso_max_size was added in the blamed commit.

The issue even occurs if all values in skb_ext_type_len[] are "0", ruling out the possibility of an actual overflow.

2023-12-21posix-timers: Get rid of [COMPAT_]SYS_NI() usesLinus Torvalds6-96/+19
Only the posix timer system calls use this (when the posix timer support is disabled, which does not actually happen in any normal case), because they had debug code to print out a warning about missing system calls. Get rid of that special case, and just use the standard COND_SYSCALL interface that creates weak system call stubs that return -ENOSYS for when the system call does not exist. This fixes a kCFI issue with the SYS_NI() hackery: CFI failure at int80_emulation+0x67/0xb0 (target: sys_ni_posix_timers+0x0/0x70; expected type: 0xb02b34d9) WARNING: CPU: 0 PID: 48 at int80_emulation+0x67/0xb0 Reported-by: kernel test robot <oliver.sang@intel.com> Reviewed-by: Sami Tolvanen <samitolvanen@google.com> Tested-by: Sami Tolvanen <samitolvanen@google.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Dave Hansen <dave.hansen@linux.intel.com> Cc: Borislav Petkov <bp@alien8.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Each RQ can be attached to a queue counter only within the same vhca. To still cover all RQs with these counters, we create multiple instances, one per vhca.

2023-12-21net/mlx5e: Let channels be SD-awareTariq Toukan8-27/+35
Distribute the channels between the different SD-devices to acheive local numa node performance on multiple numas. Each channel works against one specific mdev, creating all datapath queues against it. We distribute channels to mdevs in a round-robin policy. Example for 2 mdevs and 6 channels: +-------+---------+ | ch ix | mdev ix | +-------+---------+ | 0 | 0 | | 1 | 1 | | 2 | 0 | | 3 | 1 | | 4 | 0 | | 5 | 1 | +-------+---------+ This round-robin distribution policy is preferred over another suggested intuitive distribution, in which we first distribute one half of the channels to mdev #0 and then the second half to mdev #1. We prefer round-robin for a reason: it is less influenced by changes in the number of channels. The mapping between channel index and mdev is fixed, no matter how many channels the user configures. As the channel stats are persistent to channels closure, changing the mapping every single time would turn the accumulative stats less representing of the channel's history. Per-channel objects should stop using the primary mdev (priv->mdev) directly, and instead move to using their own channel's mdev.

While the SD multiple devices are used to avoid cross-numa memory, when it comes to chip level all traffic goes only through the primary device. The secondaries are forced to silent mode, to guarantee they are not involved in any unexpected ingress/egress traffic. In RX, secondary devices will not have steering objects. Traffic will be steered from the primary device to the RQs of a secondary device using advanced cross-vhca RX steering capabilities.

Once all devices of a component are registered, the component becomes ready, and a primary device is elected.

Patch series "Three memory-failure fixes". I've been looking at the memory-failure code and I believe I have found three bugs that need fixing -- one going all the way back to 2010! I'll have more patches later to use folios more extensively but didn't want these bugfixes to get caught up in that. This patch (of 3): Both collect_procs_anon() and collect_procs_file() iterate over the VMA interval trees looking for a single pgoff, so it is wrong to look for the pgoff of the head page as is currently done. However, it is also wrong to look at page->mapping of the precise page as this is invalid for tail pages. Clear up the confusion by passing both the folio and the precise page to collect_procs().

The "locked-in-memory size" limit per process can be non-multiple of page_size. The mmap() fails if we try to allocate locked-in-memory with same size as the allowed limit if it isn't multiple of the page_size because mmap() rounds off the memory size to be allocated to next multiple of page_size. Fix this by flooring the length to be allocated with mmap() to the previous multiple of the page_size. This was getting triggered on KernelCI regularly because of different ulimit settings which wasn't multiple of the page_size.

2023-12-21mm: migrate high-order folios in swap cache correctlyCharan Teja Kalla1-1/+8
Large folios occupy N consecutive entries in the swap cache instead of using multi-index entries like the page cache. However, if a large folio is re-added to the LRU list, it can be migrated. The migration code was not aware of the difference between the swap cache and the page cache and assumed that a single xas_store() would be sufficient. This leaves potentially many stale pointers to the now-migrated folio in the swap cache, which can lead to almost arbitrary data corruption in the future. This can also manifest as infinite loops with the RCU read lock held.

mas_preallocate() defaults to requesting 1 node for preallocation and then ,depending on the type of store, will update the request variable. There isn't a check for a slot store type, so slot stores are preallocating the default 1 node. Slot stores do not require any additional nodes, so add a check for the slot store case that will bypass node_count_gfp(). Update the tests to reflect that slot stores do not require allocations.
