2020-03-18locks: reinstate locks_delete_block optimizationLinus Torvalds2-7/+50
There is measurable performance impact in some synthetic tests due to commit 6d390e4b5d48 (locks: fix a potential use-after-free problem when wakeup a waiter). Fix the race condition instead by clearing the fl_blocker pointer after the wake_up, using explicit acquire/release semantics. This does mean that we can no longer use the clearing of fl_blocker as the wait condition, so switch the waiters over to checking whether the fl_blocked_member list_head is empty.

2020-03-19modpost: Get proper section index by get_secindex() instead of st_shndxXiao Yang1-1/+2
(uint16_t) st_shndx is limited to 65535(i.e. SHN_XINDEX) so sym_get_data() gets wrong section index by st_shndx if requested symbol contains extended section index that is more than 65535. In this case, we need to get proper section index by .symtab_shndx section. Module.symvers generated by building kernel with "-ffunction-sections -fdata-sections" shows the issue.

2020-03-18mm: slub: be more careful about the double cmpxchg of freelistLinus Torvalds1-2/+4
This is just a cleanup addition to Jann's fix to properly update the transaction ID for the slub slowpath in commit fd4d9c7d0c71 ("mm: slub: add missing TID bump.."). The transaction ID is what protects us against any concurrent accesses, but we should really also make sure to make the 'freelist' comparison itself always use the same freelist value that we then used as the new next free pointer. Jann points out that if we do all of this carefully, we could skip the transaction ID update for all the paths that only remove entries from the lists, and only update the TID when adding entries (to avoid the ABA issue with cmpxchg and list handling re-adding a previously seen value). But this patch just does the "make sure to cmpxchg the same value we used" rather than then try to be clever.

2020-03-18mm: slub: add missing TID bump in kmem_cache_alloc_bulk()Jann Horn1-0/+9
When kmem_cache_alloc_bulk() attempts to allocate N objects from a percpu freelist of length M, and N > M > 0, it will first remove the M elements from the percpu freelist, then call ___slab_alloc() to allocate the next element and repopulate the percpu freelist. ___slab_alloc() can re-enable IRQs via allocate_slab(), so the TID must be bumped before ___slab_alloc() to properly commit the freelist head change. Fix it by unconditionally bumping c->tid when entering the slowpath.

2020-03-18tty: fix compat TIOCGSERIAL checking wrong function ptrEric Biggers1-1/+1
Commit 77654350306a ("take compat TIOC[SG]SERIAL treatment into tty_compat_ioctl()") changed the compat version of TIOCGSERIAL to start checking for the presence of the ->set_serial function pointer rather than ->get_serial. This appears to be a copy-and-paste error, since ->get_serial is the function pointer that is called as well as the pointer that is checked by the non-compat version of TIOCGSERIAL. Fix this by checking the correct function pointer.

2020-03-17arm64: smp: fix crash_smp_send_stop() behaviourCristian Marussi1-2/+6
On a system configured to trigger a crash_kexec() reboot, when only one CPU is online and another CPU panics while starting-up, crash_smp_send_stop() will fail to send any STOP message to the other already online core, resulting in fail to freeze and registers not properly saved. Moreover even if the proper messages are sent (case CPUs > 2) it will similarly fail to account for the booting CPU when executing the final stop wait-loop, so potentially resulting in some CPU not been waited for shutdown before rebooting. A tangible effect of this behaviour can be observed when, after a panic with kexec enabled and loaded, on the following reboot triggered by kexec, the cpu that could not be successfully stopped fails to come back online: [ 362.291022] ------------[ cut here ]------------ [ 362.291525] kernel BUG at arch/arm64/kernel/cpufeature.c:886!

By default, tty_port_init() initializes those parameters to a multiple of HZ. For instance in line 69 of tty_port.c: port->close_delay = (50 * HZ) / 100; https://github.com/torvalds/linux/blob/master/drivers/tty/tty_port.c#L69 With e.g. CONFIG_HZ = 250 (as this is the case for Ubuntu 18.04 linux-image-4.15.0-37-generic), the default setting for close_delay is thus 125. When ioctl(fd, TIOCGSERIAL, &s) is executed, the setting returned in user space is '12' (125/10). When ioctl(fd, TIOCSSERIAL, &s) is then executed with the same setting '12', the value is interpreted as '120' which is different from the current setting and a EPERM error may be raised by set_serial_info() if !CAP_SYS_ADMIN. https://github.com/torvalds/linux/blob/master/drivers/usb/class/cdc-acm.c#L919 Fixes: ba2d8ce9db0a6 ("cdc-acm: implement TIOCSSERIAL to avoid blocking close(2)") Signed-off-by: Anthony Mallet <anthony.mallet@laas.fr> Cc: stable <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20200312133101.7096-2-anthony.mallet@laas.fr Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Some users have tried adding usbcore.quirks=0bda:8153:k to the kernel commandline and all users who have tried this report that this fixes this. Also note that we already have an existing NO_LPM quirk for the RTL8153 used in the Microsoft Surface Dock (where it uses a different usb-id). This commit adds a NO_LPM quirk for the generic Realtek RTL8153 0bda:8153 usb-id, fixing the Tx timeout errors on these devices.

2020-03-17CIFS: Increment num_remote_opens stats counter even in case of smb2_query_dir_firstShyam Prasad N1-0/+2
The num_remote_opens counter keeps track of the number of open files which must be maintained by the server at any point. This is a per-tree-connect counter, and the value of this counter gets displayed in the /proc/fs/cifs/Stats output as a following... Open files: 0 total (local), 1 open on server ^^^^^^^^^^^^^^^^ As a thumb-rule, we want to increment this counter for each open/create that we successfully execute on the server. Similarly, we should decrement the counter when we successfully execute a close. In this case, an increment was being missed in case of smb2_query_dir_first, in case of successful open. As a result, we would underflow the counter and we could even see the counter go to negative after sufficient smb2_query_dir_first calls. I tested the stats counter for a bunch of filesystem operations with the fix. And it looks like the counter looks correct to me. I also check if we missed the increments and decrements elsewhere. It does not seem so. Few other cases where an open is done and we don't increment the counter are the compound calls where the corresponding close is also sent in the request.

2020-03-17mmc: sdhci-acpi: Switch signal voltage back to 3.3V on suspend on external microSD on Lenovo Miix 320Hans de Goede1-2/+66
Based on a sample of 7 DSDTs from Cherry Trail devices using an AXP288 PMIC depending on the design one of 2 possible LDOs on the PMIC is used for the MMC signalling voltage, either DLDO3 or GPIO1LDO (GPIO1 pin in low noise LDO mode). The Lenovo Miix 320-10ICR uses GPIO1LDO in the SHC1 ACPI device's DSM methods to set 3.3 or 1.8 signalling voltage and this appears to work as advertised, so presumably the device is actually using GPIO1LDO for the external microSD signalling voltage. But this device has a bug in the _PS0 method of the SHC1 ACPI device, the DSM remembers the last set signalling voltage and the _PS0 restores this after a (runtime) suspend-resume cycle, but it "restores" the voltage on DLDO3 instead of setting it on GPIO1LDO as the DSM method does. DLDO3 is used for the LCD and setting it to 1.8V causes the LCD to go black. This commit works around this issue by calling the Intel DSM to reset the signal voltage to 3.3V after the host has been runtime suspended. This will make the _PS0 method reprogram the DLDO3 voltage to 3.3V, which leaves it at its original setting fixing the LCD going black. This commit adds and uses a DMI quirk mechanism to only trigger this workaround on the Lenovo Miix 320 while leaving the behavior of the driver unchanged on other devices.

2020-03-17initramfs: restore default compression behaviorEugeniy Paltsev1-11/+11
Even though INITRAMFS_SOURCE kconfig option isn't set in most of defconfigs it is used (set) extensively by various build systems. Commit f26661e12765 ("initramfs: make initramfs compression choice non-optional") has changed default compression mode. Previously we compress initramfs using available compression algorithm. Now we don't use any compression at all by default. It significantly increases the image size in case of build system chooses embedded initramfs. Initially I faced with this issue while using buildroot. As of today it's not possible to set preferred compression mode in target defconfig as this option depends on INITRAMFS_SOURCE being set. Modification of all build systems either doesn't look like good option. Let's instead rewrite initramfs compression mode choices list the way that "INITRAMFS_COMPRESSION_NONE" will be the last option in the list. In that case it will be chosen only if all other options (which implements any compression) are not available.

2020-03-17modpost: move the namespace field in Module.symvers lastJessica Yu3-15/+15
In order to preserve backwards compatability with kmod tools, we have to move the namespace field in Module.symvers last, as the depmod -e -E option looks at the first three fields in Module.symvers to check symbol versions (and it's expected they stay in the original order of crc, symbol, module). In addition, update an ancient comment above read_dump() in modpost that suggested that the export type field in Module.symvers was optional. I suspect that there were historical reasons behind that comment that are no longer accurate. We have been unconditionally printing the export type since 2.6.18 (commit bd5cbcedf44), which is over a decade ago now. Fix up read_dump() to treat each field as non-optional. I suspect the original read_dump() code treated the export field as optional in order to support pre <= 2.6.18 Module.symvers (which did not have the export type field). Note that although symbol namespaces are optional, the field will not be omitted from Module.symvers if a symbol does not have a namespace. In this case, the field will simply be empty and the next delimiter or end of line will follow.

2020-03-16ALSA: seq: oss: Fix running status after receiving sysexTakashi Iwai1-0/+1
This is a similar bug like the previous case for virmidi: the invalid running status is kept after receiving a sysex message. Again the fix is to clear the running status after handling the sysex.

2020-03-16ALSA: seq: virmidi: Fix running status after receiving sysexTakashi Iwai1-0/+1
The virmidi driver handles sysex event exceptionally in a short-cut snd_seq_dump_var_event() call, but this missed the reset of the running status. As a result, it may lead to an incomplete command right after the sysex when an event with the same running status was queued. Fix it by clearing the running status properly via alling snd_midi_event_reset_decode() for that code path.
