Thanks to all the work that was done by Andy Lutomirski and others, enter_from_user_mode() and prepare_exit_to_usermode() are now called only with interrupts disabled. Let's provide them a version of user_enter()/user_exit() that skips saving and restoring the interrupt flag. On an AMD-based machine I tested this patch on, with force-enabled context tracking, the speed-up in system calls was 90 clock cycles or 6%, measured with the following simple benchmark: #include <sys/signal.h> #include <time.h> #include <unistd.h> #include <stdio.h> unsigned long rdtsc() { unsigned long result; asm volatile("rdtsc; shl $32, %%rdx; mov %%eax, %%eax\n" "or %%rdx, %%rax" : "=a" (result) : : "rdx"); return result; } int main() { unsigned long tsc1, tsc2; int pid = getpid(); int i; tsc1 = rdtsc(); for (i = 0; i < 100000000; i++) kill(pid, SIGWINCH); tsc2 = rdtsc(); printf("%ld\n", tsc2 - tsc1); } Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Reviewed-by: NRik van Riel <riel@redhat.com> Reviewed-by: NAndy Lutomirski <luto@kernel.org> Acked-by: NPaolo Bonzini <pbonzini@redhat.com> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Gerst <brgerst@gmail.com> Cc: Denys Vlasenko <dvlasenk@redhat.com> Cc: H.

As of Xen 4.7 PV CPUID doesn't expose either of CPUID[1].ECX[7] and CPUID[0x80000007].EDX[7] anymore, causing the driver to fail to load on both Intel and AMD systems. Doing any kind of hardware capability checks in the driver as a prerequisite was wrong anyway: With the hypervisor being in charge, all such checking should be done by it. If ACPI data gets uploaded despite some missing capability, the hypervisor is free to ignore part or all of that data. Ditch the entire check_prereq() function, and do the only valid check (xen_initial_domain()) in the caller in its place.

xenbus_dev_request_and_reply() needs to track whether a transaction is open. For XS_TRANSACTION_START messages it calls transaction_start() and for XS_TRANSACTION_END messages it calls transaction_end(). If sending an XS_TRANSACTION_START message fails or responds with an an error, the transaction is not open and transaction_end() must be called. If sending an XS_TRANSACTION_END message fails, the transaction is still open, but if an error response is returned the transaction is closed. Commit 027bd7e8 ("xen/xenbus: Avoid synchronous wait on XenBus stalling shutdown/restart") introduced a regression where failed XS_TRANSACTION_START messages were leaving the transaction open. This can cause problems with suspend (and migration) as all transactions must be closed before suspending. It appears that the problematic change was added accidentally, so just remove it.

When proc_pid_attr_write() was changed to use memdup_user apparmor's (interface violating) assumption that the setprocattr buffer was always a single page was violated. The size test is not strictly speaking needed as proc_pid_attr_write() will reject anything larger, but for the sake of robustness we can keep it in. SMACK and SELinux look safe to me, but somebody else should probably have a look just in case.

由 Mark Rutland 提交于
The following commit: 66eb579e ("perf: allow for PMU-specific event filtering") added the pmu::filter_match() callback. This was intended to avoid HW constraints on events from resulting in extremely pessimistic scheduling. However, pmu::filter_match() is only called for the leader of each event group. When the leader is a SW event, we do not filter the groups, and may fail at pmu::add() time, and when this happens we'll give up on scheduling any event groups later in the list until they are rotated ahead of the failing group. This can result in extremely sub-optimal event scheduling behaviour, e.g. if running the following on a big.LITTLE platform: $ taskset -c 0 ./perf stat \ -e 'a57{context-switches,armv8_cortex_a57/config=0x11/}' \ -e 'a53{context-switches,armv8_cortex_a53/config=0x11/}' \ ls <not counted> context-switches (0.00%) <not counted> armv8_cortex_a57/config=0x11/ (0.00%) 24 context-switches (37.36%) 57589154 armv8_cortex_a53/config=0x11/ (37.36%) Here the 'a53' event group was always eligible to be scheduled, but the 'a57' group never eligible to be scheduled, as the task was always affine to a Cortex-A53 CPU. The SW (group leader) event in the 'a57' group was eligible, but the HW event failed at pmu::add() time, resulting in ctx_flexible_sched_in giving up on scheduling further groups with HW events. One way of avoiding this is to check pmu::filter_match() on siblings as well as the group leader. If any of these fail their pmu::filter_match() call, we must skip the entire group before attempting to add any events.
