commit fd7f6727 upstream. I don't think it makes sense for a module to have a soft dependency on itself. This seems quite cyclic by nature and I can't see what purpose it could serve. OTOH libcrc32c calls crypto_alloc_shash("crc32c", 0, 0) so it pretty much assumes that some incarnation of the "crc32c" hash algorithm has been loaded. Therefore it makes sense to have the soft dependency there (as crc-t10dif does.) Cc: Tim Chen <tim.c.chen@linux.intel.com> Cc: "David S. Miller" <davem@davemloft.net> Signed-off-by:

commit a6a48c56 upstream. This patch forbids the calling of bind(2) when there are child sockets created by accept(2) in existence, even if they are created on the nokey path. This is needed as those child sockets have references to the tfm object which bind(2) will destroy. Signed-off-by:

commit 566d1827 upstream. Some early controllers incorrectly reported zero ports in PORTS_IMPL register and the ahci driver fabricates PORTS_IMPL from the number of ports in those cases. This hasn't mattered but with the new nvme controllers there are cases where zero PORTS_IMPL is valid and should be honored. Disable the workaround for >= AHCI 1.3. Signed-off-by:

commit 6de62f15 upstream. Hash implementations that require a key may crash if you use them without setting a key. This patch adds the necessary checks so that if you do attempt to use them without a key that we return -ENOKEY instead of proceeding. This patch also adds a compatibility path to support old applications that do acept(2) before setkey. Signed-off-by:

commit a383292c upstream. When we fail an accept(2) call we will end up freeing the socket twice, once due to the direct sk_free call and once again through newsock. This patch fixes this by removing the sk_free call. Reported-by:

Herbert Xu authored
commit c840ac6a upstream. Each af_alg parent socket obtained by socket(2) corresponds to a tfm object once bind(2) has succeeded. An accept(2) call on that parent socket creates a context which then uses the tfm object. Therefore as long as any child sockets created by accept(2) exist the parent socket must not be modified or freed. This patch guarantees this by using locks and a reference count on the parent socket. Any attempt to modify the parent socket will fail with EBUSY. Reported-by:

commit 9c03ee14 upstream. The following PowerPC commit: c118baf8 ("arch/powerpc/mm/numa.c: do not allocate bootmem memory for non existing nodes") avoids allocating bootmem memory for non existent nodes. But when DEBUG_PER_CPU_MAPS=y is enabled, my powerNV system failed to boot because in sched_init_numa(), cpumask_or() operation was done on unallocated nodes. Fix that by making cpumask_or() operation only on existing nodes. [ Tested with and w/o DEBUG_PER_CPU_MAPS=y on x86 and PowerPC. ] Reported-by:

commit 12c2ab09 upstream. When tearing down page tables, we return early for the final level since we know that we won't have any table pointers to follow. Unfortunately, this also means that we forget to free the final level, so we end up leaking memory. Fix the issue by always freeing the current level, but just don't bother to iterate over the ptes if we're at the final level. Reported-by:

commit 5c17c861 upstream. ioctl(TIOCGETD) retrieves the line discipline id directly from the ldisc because the line discipline id (c_line) in termios is untrustworthy; userspace may have set termios via ioctl(TCSETS*) without actually changing the line discipline via ioctl(TIOCSETD). However, directly accessing the current ldisc via tty->ldisc is unsafe; the ldisc ptr dereferenced may be stale if the line discipline is changing via ioctl(TIOCSETD) or hangup. Wait for the line discipline reference (just like read() or write()) to retrieve the "current" line discipline id. Signed-off-by:

commit 7f22f6c9 upstream. A small window exists where a tty reopen will observe the tty just prior to imminent teardown (tty->count == 0); in this case, open() returns EIO to userspace. Instead, retry the open after checking for signals and yielding; this interruptible retry loop allows teardown to commence and initialize a new tty on retry. Never retry the BSD master pty reopen; there is no guarantee the pty pair teardown is imminent since the slave file descriptors may remain open indefinitely. Signed-off-by:

commit 6d27a63c upstream. Although n_tty_check_unthrottle() has a valid ldisc reference (since the tty core gets the ldisc ref in tty_read() before calling the line discipline read() method), it does not have a valid ldisc reference to the "other" pty of a pty pair. Since getting an ldisc reference for tty->link essentially open-codes tty_wakeup(), just replace with the equivalent tty_wakeup(). Signed-off-by:

commit a38a08df upstream. This driver registers for extcon events as part of its probe, but never unregisters them in case of error in the probe path. There were multiple issues noticed due to this missing error handling. One of them is random crashes if the regulators are not ready yet by the time probe is invoked. Ivan's previous attempt [1] to fix this issue, did not really address all the failure cases like regualtor/get_irq failures.

commit 19454462 upstream. In current acm driver, the bulk-in callback function ignores the URBs unlinked in usb core. This causes unexpected data loss in some cases. For example, runtime suspend entry will unlinked all urbs and set urb->status to -ENOENT even those urbs might have data not processed yet. Hence, data loss occurs. This patch lets bulk-in callback function handle unlinked urbs to avoid data loss. Signed-off-by:

commit d8f00cd6 upstream. In function usb_reset_and_verify_device, the old BOS descriptor may still be used before allocating a new one. (usb_unlocked_disable_lpm function uses it under the situation that it fails to disable lpm.) So we cannot set the udev->bos to NULL before that, just keep what it was. It will be overwrite when allocating a new one.
