[PATCH] LoongArch: module: set section addresses to 0x0

by Huacai Chen

These got*, plt* and .text.ftrace_trampoline sections specified for LoongArch have non-zero addressses. Non-zero section addresses in a relocatable ELF would confuse GDB when it tries to compute the section offsets and it ends up printing wrong symbol addresses. Therefore, set them to zero, which mirrors the change in commit 5d8591bc0fbaeb6ded ("arm64 module: set plt* section addresses to 0x0").

[PATCH] md/raid10: fix deadlock when handle read error and running data-check at same time

by linminggui

when running data-check and ecounter a normal IO errror, raid10d handle the error, one resync IO added into conf->retry_list waiting for raid10d to handle it, so barrier will not drop to zero and the normal IO(read error) will stuck in wait_barrier in raid10_read_request. after this, resyc thread will stuck in raise_barrier, other process will stuck in wait_barrier.

[PATCH v2] mm/swap: fix swap_info_struct race between swapoff and get_swap_pages()

by Rongwei Wang

The si->lock must be held when deleting the si from the available list. Otherwise, another thread can re-add the si to the available list, which can lead to memory corruption. The only place we have found where this happens is in the swapoff path. This case can be described as below: core 0 core 1 swapoff del_from_avail_list(si) waiting try lock si->lock acquire swap_avail_lock and re-add si into swap_avail_head acquire si->lock but missing si already be added again, and continuing to clear SWP_WRITEOK, etc. It can be easily found a massive warning messages can be triggered inside get_swap_pages() by some special cases, for example, we call madvise(MADV_PAGEOUT) on blocks of touched memory concurrently, meanwhile, run much swapon-swapoff operations (e.g. stress-ng-swap). However, in the worst case, panic can be caused by the above scene. In swapoff(), the memory used by si could be kept in swap_info[] after turning off a swap. This means memory corruption will not be caused immediately until allocated and reset for a new swap in the swapon path. A panic message caused: (with CONFIG_PLIST_DEBUG enabled) ------------[ cut here ]------------ top: 00000000e58a3003, n: 0000000013e75cda, p: 000000008cd4451a prev: 0000000035b1e58a, n: 000000008cd4451a, p: 000000002150ee8d next: 000000008cd4451a, n: 000000008cd4451a, p: 000000008cd4451a WARNING: CPU: 21 PID: 1843 at lib/plist.c:60 plist_check_prev_next_node+0x50/0x70 Modules linked in: rfkill(E) crct10dif_ce(E)...

[PATCH net] net: sfp: initialize sfp->i2c_block_size at sfp allocation

by Ivan Bornyakov

sfp->i2c_block_size is initialized at SFP module insertion in sfp_sm_mod_probe(). Because of that, if SFP module was not inserted since boot, ethtool -m leads to zero-length I2C read attempt. # ethtool -m xge0 i2c i2c-3: adapter quirk: no zero length (addr 0x0050, size 0, read) Cannot get Module EEPROM data: Operation not supported If SFP module was plugged then removed at least once, sfp->i2c_block_size will be initialized and ethtool -m will fail with different error # ethtool -m xge0 Cannot get Module EEPROM data: Remote I/O error Fix this by initializing sfp->i2_block_size at struct sfp allocation stage so ethtool -m with SFP module removed will fail the same way, i.e. -EREMOTEIO, in both cases and without errors from I2C adapter.

+ mm-huge_memoryc-warn-with-pr_warn_ratelimited-instead-of-vm_warn_on_once_folio.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: mm/huge_memory.c: warn with pr_warn_ratelimited instead of VM_WARN_ON_ONCE_FOLIO has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-huge_memoryc-warn-with-pr_warn_ratelimited-instead-of-vm_warn_on_once_folio.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Naoya Horiguchi <naoya.horiguchi(a)nec.com> Subject: mm/huge_memory.c: warn with pr_warn_ratelimited instead of VM_WARN_ON_ONCE_FOLIO Date: Thu, 6 Apr 2023 17:20:04 +0900 split_huge_page_to_list() WARNs when called for huge zero pages, which sounds to me too harsh because it does not imply a kernel bug, but just notifies the event to admins. On the other hand, this is considered as critical by syzkaller and makes its testing less efficient, which seems to me harmful. So replace the VM_WARN_ON_ONCE_FOLIO with pr_warn_ratelimited.
