2018-11-13tpm1: reimplement tpm1_continue_selftest() using tpm_bufTomas Winkler2-20/+10
Reimplement tpm1_continue_selftest() using tpm_buf structure. This is the last command using the old tpm_cmd_t structure and now the structure can be removed.

2018-11-11net: dsa: mv88e6xxx: Fix clearing of stats countersAndrew Lunn1-0/+2
The mv88e6161 would sometime fail to probe with a timeout waiting for the switch to complete an operation. This operation is supposed to clear the statistics counters. However, due to a read/modify/write, without the needed mask, the operation actually carried out was more random, with invalid parameters, resulting in the switch not responding. We need to preserve the histogram mode bits, so apply a mask to keep them.

2018-11-11tipc: fix link re-establish failureJon Maloy1-4/+7
When a link failure is detected locally, the link is reset, the flag link->in_session is set to false, and a RESET_MSG with the 'stopping' bit set is sent to the peer. The purpose of this bit is to inform the peer that this endpoint just is going down, and that the peer should handle the reception of this particular RESET message as a local failure. This forces the peer to accept another RESET or ACTIVATE message from this endpoint before it can re-establish the link. This again is necessary to ensure that link session numbers are properly exchanged before the link comes up again. If a failure is detected locally at the same time at the peer endpoint this will do the same, which is also a correct behavior. However, when receiving such messages, the endpoints will not distinguish between 'stopping' RESETs and ordinary ones when it comes to updating session numbers. Both endpoints will copy the received session number and set their 'in_session' flags to true at the reception, while they are still expecting another RESET from the peer before they can go ahead and re-establish. This is contradictory, since, after applying the validation check referred to below, the 'in_session' flag will cause rejection of all such messages, and the link will never come up again. We now fix this by not only handling received RESET/STOPPING messages as a local failure, but also by omitting to set a new session number and the 'in_session' flag in such cases.

2018-11-11builddeb: Fix inclusion of dtbs in debian packageRob Herring1-2/+2
Commit 37c8a5fafa3b ("kbuild: consolidate Devicetree dtb build rules") moved the location of 'dtbs_install' target which caused dtbs to not be installed when building debian package with 'bindeb-pkg' target. Update the builddeb script to use the same logic that determines if there's a 'dtbs_install' target which is presence of the arch dts directory. Also, use CONFIG_OF_EARLY_FLATTREE instead of CONFIG_OF as that's a better indication of whether we are building dtbs. This commit will also have the side effect of installing dtbs on any arch that has dts files. Previously, it was dependent on whether the arch defined 'dtbs_install'.

2018-11-11Revert "scripts/setlocalversion: git: Make -dirty check more robust"Guenter Roeck1-1/+1
This reverts commit 6147b1cf19651c7de297e69108b141fb30aa2349. The reverted patch results in attempted write access to the source repository, even if that repository is mounted read-only. Output from "strace git status -uno --porcelain": getcwd("/tmp/linux-test", 129) = 16 open("/tmp/linux-test/.git/index.lock", O_RDWR|O_CREAT|O_EXCL|O_CLOEXEC, 0666) = -1 EROFS (Read-only file system) While git appears to be able to handle this situation, a monitored build environment (such as the one used for Chrome OS kernel builds) may detect it and bail out with an access violation error. On top of that, the attempted write access suggests that git _will_ write to the file even if a build output directory is specified. Users may have the reasonable expectation that the source repository remains untouched in that situation.

Since commit b41d920acff8 ("kbuild: deb-pkg: split generating packaging and build"), the build version of the kernel contained in a deb package is too low by 1. Prior to the bad commit, the kernel was built first, then the number in .version file was read out, and written into the debian control file. Now, the debian control file is created before the kernel is actually compiled, which is causing the version number mismatch. Let the mkdebian script pass KBUILD_BUILD_VERSION=${revision} to require the build system to use the specified version number.

2018-11-09x86/cpu/vmware: Do not trace vmware_sched_clock()Steven Rostedt (VMware)1-1/+1
When running function tracing on a Linux guest running on VMware Workstation, the guest would crash. This is due to tracing of the sched_clock internal call of the VMware vmware_sched_clock(), which causes an infinite recursion within the tracing code (clock calls must not be traced). Make vmware_sched_clock() not traced by ftrace.

According to Ted Ts'o ext4_getblk() called in ext4_xattr_inode_write() should not return bh = NULL The only time that bh could be NULL, then, would be in the case of something really going wrong; a programming error elsewhere (perhaps a wild pointer dereference) or I/O error causing on-disk file system corruption (although that would be highly unlikely given that we had *just* allocated the blocks and so the metadata blocks in question probably would still be in the cache).

2018-11-09xen: remove size limit of privcmd-buf mapping interfaceJuergen Gross1-18/+4
Currently the size of hypercall buffers allocated via /dev/xen/hypercall is limited to a default of 64 memory pages. For live migration of guests this might be too small as the page dirty bitmask needs to be sized according to the size of the guest. This means migrating a 8GB sized guest is already exhausting the default buffer size for the dirty bitmap. There is no sensible way to set a sane limit, so just remove it completely. The device node's usage is limited to root anyway, so there is no additional DOS scenario added by allowing unlimited buffers. While at it make the error path for the -ENOMEM case a little bit cleaner by setting n_pages to the number of successfully allocated pages instead of the target size.

2018-11-09xen: fix xen_qlock_wait()Juergen Gross1-6/+8
Commit a856531951dc80 ("xen: make xen_qlock_wait() nestable") introduced a regression for Xen guests running fully virtualized (HVM or PVH mode). The Xen hypervisor wouldn't return from the poll hypercall with interrupts disabled in case of an interrupt (for PV guests it does). So instead of disabling interrupts in xen_qlock_wait() use a nesting counter to avoid calling xen_clear_irq_pending() in case xen_qlock_wait() is nested.
