In prior kernels, we did file assignment always at prep time. This meant that req->task == current. But after deferring that assignment and then pushing the inflight tracking back in, we've got the inflight tracking using current when it should in fact now be using req->task. Fixup that error introduced by adding the inflight tracking back after file assignments got modifed. Fixes: 9cae36a0 ("io_uring: reinstate the inflight tracking") Signed-off-by:

Commit 793917d9 ("mm/readahead: Add large folio readahead") introduced support for using large folios for filebacked pages if the filesystem supports it. page_cache_ra_order() was introduced to allocate and add these large folios to the page cache. However adding pages to the page cache should be serialized against truncation and hole punching by taking invalidate_lock. Not doing so can lead to data races resulting in stale data getting added to the page cache and marked up-to-date. See commit 730633f0 ("mm: Protect operations adding pages to page cache with invalidate_lock") for more details. This issue was found by inspection but a testcase revealed it was possible to observe in practice on XFS. Fix this by taking invalidate_lock in page_cache_ra_order(), to mirror what is done for the non-thp case in page_cache_ra_unbounded(). Signed-off-by:

In our efforts to remove uses of PG_private, we have found folios with the private flag clear and folio->private not-NULL. That is the root cause behind 642d51fb ("ceph: check folio PG_private bit instead of folio->private"). It can also affect a few other filesystems that haven't yet reported a problem. compaction_alloc() can return a page with uninitialised page->private, and rather than checking all the callers of migrate_pages(), just zero page->private after calling get_new_page(). Similarly, the tail pages from split_huge_page() may also have an uninitialised page->private. Reported-by:

When a packet enters the OVS datapath and does not match any existing flows installed in the kernel flow cache, the packet will be sent to userspace to be parsed, and a new flow will be created. The kernel and OVS rely on each other to parse packet fields in the same way so that packets will be handled properly. As per the design document linked below, OVS expects all later IPv6 fragments to have nw_proto=44 in the flow key, so they can be correctly matched on OpenFlow rules. OpenFlow controllers create pipelines based on this design. This behavior was changed by the commit in the Fixes tag so that nw_proto equals the next_header field of the last extension header. However, there is no counterpart for this change in OVS userspace, meaning that this field is parsed differently between OVS and the kernel. This is a problem because OVS creates actions based on what is parsed in userspace, but the kernel-provided flow key is used as a match criteria, as described in Documentation/networking/openvswitch.rst. This leads to issues such as packets incorrectly matching on a flow and thus the wrong list of actions being applied to the packet. Such changes in packet parsing cannot be implemented without breaking the userspace. The offending commit is partially reverted to restore the expected behavior. The change technically made sense and there is a good reason that it was implemented, but it does not comply with the original design of OVS. If in the future someone wants to implement such a change, then it must be user-configurable and disabled by default to preserve backwards compatibility with existing OVS versions.

Commit 8a59f9d1 ("sock: Introduce sk->sk_prot->psock_update_sk_prot()") has moved the inet_csk_has_ulp(sk) check from sk_psock_init() to the new tcp_bpf_update_proto() function. I'm guessing that this was done to allow creating psocks for non-inet sockets. Unfortunately the destruction path for psock includes the ULP unwind, so we need to fail the sk_psock_init() itself. Otherwise if ULP is already present we'll notice that later, and call tcp_update_ulp() with the sk_proto of the ULP itself, which will most likely result in the ULP looping its callbacks.

The following sequence currently causes a driver bug warning when using virtio_net: # ip link set eth0 up # echo mem > /sys/power/state (or e.g. # rtcwake -s 10 -m mem) <resume> # ip link set eth0 down Missing register, driver bug WARNING: CPU: 0 PID: 375 at net/core/xdp.c:138 xdp_rxq_info_unreg+0x58/0x60 Call trace: xdp_rxq_info_unreg+0x58/0x60 virtnet_close+0x58/0xac __dev_close_many+0xac/0x140 __dev_change_flags+0xd8/0x210 dev_change_flags+0x24/0x64 do_setlink+0x230/0xdd0 ... This happens because virtnet_freeze() frees the receive_queue completely (including struct xdp_rxq_info) but does not call xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets up the receive_queue again but does not call xdp_rxq_info_reg(). Actually, parts of virtnet_freeze_down() and virtnet_restore_up() are almost identical to virtnet_close() and virtnet_open(): only the calls to xdp_rxq_info_(un)reg() are missing. This means that we can fix this easily and avoid such problems in the future by just calling virtnet_close()/open() from the freeze/restore handlers. Aside from adding the missing xdp_rxq_info calls the only difference is that the refill work is only cancelled if netif_running(). However, this should not make any functional difference since the refill work should only be active if the network interface is actually up.

Intel I210 on some Intel Alder Lake platforms can only achieve ~750Mbps Tx speed via iperf. The RR2DCDELAY shows around 0x2xxx DMA delay, which will be significantly lower when 1) ASPM is disabled or 2) SoC package c-state stays above PC3. When the RR2DCDELAY is around 0x1xxx the Tx speed can reach to ~950Mbps. According to the I210 datasheet "8.26.1 PCIe Misc. Register - PCIEMISC", "DMA Idle Indication" doesn't seem to tie to DMA coalesce anymore, so set it to 1b for "DMA is considered idle when there is no Rx or Tx AND when there are no TLPs indicating that CPU is active detected on the PCIe link (such as the host executes CSR or Configuration register read or write operation)" and performing Tx should also fall under "active CPU on PCIe link" case. In addition to that, commit b6e0c419 ("igb: Move DMA Coalescing init code to separate function.") seems to wrongly changed from enabling E1000_PCIEMISC_LX_DECISION to disabling it, also fix that.

It was discovered that the Documentation lacks of a fundamental detail on how to correctly change the MAX_FRAME_SIZE of the switch. In fact if the MAX_FRAME_SIZE is changed while the cpu port is on, the switch panics and cease to send any packet. This cause the mgmt ethernet system to not receive any packet (the slow fallback still works) and makes the device not reachable. To recover from this a switch reset is required. To correctly handle this, turn off the cpu ports before changing the MAX_FRAME_SIZE and turn on again after the value is applied.

Under CONFIG_FORTIFY_SOURCE=y and CONFIG_UBSAN_BOUNDS=y, Clang is bugged here for calculating the size of the destination buffer (0x10 instead of 0x14). This copy is a fixed size (sizeof(struct fw_section_info_st)), with the source and dest being struct fw_section_info_st, so the memcpy should be safe, assuming the index is within bounds, which is UBSAN_BOUNDS's responsibility to figure out. Avoid the whole thing and just do a direct assignment. This results in no change to the executable code.

Pull 9pfs fixes from Dominique Martinet: "A couple of fid refcount and fscache fixes: - fid refcounting was incorrect in some corner cases and would leak resources, only freed at umount time. The first three commits fix three such cases - 'cache=loose' or fscache was broken when trying to write a partial page to a file with no read permission since the rework a few releases ago. The fix taken here is just to restore old behavior of using the special 'writeback_fid' for such reads, which is open as root/RDWR and such not get complains that we try to read on a WRONLY fid. Long-term it'd be nice to get rid of this and not issue the read at all (skip cache?) in such cases, but that direction hasn't progressed" * tag '9p-for-5.19-rc4' of https://github.com/martinetd/linux: 9p: fix EBADF errors in cached mode 9p: Fix refcounting during full path walks for fid lookups 9p: fix fid refcount leak in v9fs_vfs_get_link 9p: fix fid refcount leak in v9fs_vfs_atomic_open_dotl -

This reverts commit 8fc74d18. BAR0 is the main (only?) register bank for this device. We most obviously can't unmap it before the netdev is unregistered. This was pointed out in review but the patch got reposted and merged, anyway. The author of the patch was only testing it with a QEMU model, which I presume does not emulate enough for the netdev to be brought up (author's replies are not visible in lore because they kept sending their emails in HTML).

Simon reports that if two LAN9514 USB adapters are directly connected without an intermediate switch, the link fails to come up and link LEDs remain dark. The issue was introduced by commit 1ce8b372 ("usbnet: smsc95xx: Forward PHY interrupts to PHY driver to avoid polling"). The PHY suffers from a known erratum wherein link detection becomes unreliable if Energy Detect Power-Down is used. In poll mode, the driver works around the erratum by briefly disabling EDPD for 640 msec to detect a neighbor, then re-enabling it to save power. In interrupt mode, no interrupt is signaled if EDPD is used by both link partners, so it must not be enabled at all. We'll recoup the power savings by enabling SUSPEND1 mode on affected LAN95xx chips in a forthcoming commit.

We have re-polling for partial IO, so a request can be polled twice. If it used two poll entries the first time then on the second io_arm_poll_handler() it will find the old apoll entry and NULL kmalloc()'ed second entry, i.e. apoll->double_poll, so leaking it. Fixes: 10c87333 ("io_uring: allow re-poll if we made progress") Signed-off-by:
