| | | | | | | | | | | | Split the 'video' ACPI lock up into two locks to resolve a LOR with the sysctl lock. The 'video' lock now protects the 'bus' of video output devices attached to a graphics adapter. It is used when iterating over the list of outputs, etc. The 'video_output' lock is used to lock the output-specific data similar to a driver lock for the individual video outputs.

| | | | | | | | | | | | | | | | Extend the device pager to support different memory attributes on different pages in an object. - Add a new variant of d_mmap() currently called d_mmap2() which accepts an additional in/out parameter that is the memory attribute to use for the requested page. - A driver either uses d_mmap() or d_mmap2() for all requests but not both. The current implementation uses a flag in the cdevsw (D_MMAP2) to indicate that the driver provides a d_mmap2() handler instead of d_mmap(). This is done to make the change ABI compatible with existing drivers and MFC'able to 7 and 8. Notes: svn path=/stable/8/; revision=198594

| | | | | | | | | | | | | | | | | | | | | | | | | | Random number generator initialization cleanup: - Introduce new SI_SUB_RANDOM point in boot sequence to make it clear from where one may start using random(9). It should be as early as possible, so place it just after SI_SUB_CPU where we have some randomness on most platforms via get_cyclecount(). - Move stack protector initialization to be after SI_SUB_RANDOM as before this point we have no randomness at all. This fixes stack protector to actually protect stack with some random guard value instead of a well-known one. Note that this patch doesn't try to address arc4random(9) issues. With current code, it will be implicitly seeded by stack protector and hence will get the same entropy as random(9). It will be securely reseeded once /dev/random is feeded by some entropy from userland.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Close a race with caching of -ve name lookups in the NFS client. Specifically, clients only trust -ve cache entries while the directory remains unchanged and discard any -ve cache entries for a directory when they notice that the modification time of a directory entry changes. The race involves two concurrent lookups as follows: - Thread A does a lookup for file 'foo' which sends a lookup RPC to the server. The lookup fails and the server replies. - The 'foo' file is created (either by the same client or a different client) updating the modification time on the parent directory of 'foo'. - Thread B does a lookup for a different file 'bar' which updates the cached attributes of the parent directory of 'foo' to reflect the new modification time after 'foo' was created. - Thread A finally resumes execution to parse the reply from the NFS server. It adds a -ve cache entry and sets the cached value of the directory's modification time that is used for invalidating -ve cached lookups to the new modification time set by thread B. At this point, future lookups of 'foo' will honor the -ve cached entry until the cached entry is pushed out of the name cache's LRU or the modification time of the parent directory is changed again by some other change. The fix is to read the directory's modification time before sending the lookup RPC and use that cached modification time when setting the directory's cached modification time. Also, we do not add a -ve cache entry if another thread has added -ve cache entry that set the directory's cached modification time to a newer value than the value we read before sending the lookup RPC.

| | | | | | | | | | | | | | The flow-table function flowtable_route_flush() may be called during system initialization time. Since the flow-table is designed to maintain per CPU flow cache, the existing code did not check whether "smp_started" is true before calling sched_bind() and sched_unbind(), which triggers a page fault.

In certain conditions the reference to the XPT device would not be released which would cause the usb explore thread to sleep forever on "simfree", preventing any new usb devices to be found/ejected on the bus.

| | | | | | | | | | | | | | | | | In the ARP callout timer expiration function, the current time_second is compared against the entry expiration time value (that was set based on time_second) to check if the current time is larger than the set expiration time. Due to the +/- timer granularity value, the comparison returns false, causing the alternative code to be executed. The alternative code path freed the memory without removing that entry from the table list, causing a use-after-free bug.

| | | | | | | | | | | | | | | | | | | | This patch fixes the following issues in the ARP operation: 1. There is a regression issue in the ARP code. The incomplete ARP entry was timing out too quickly (1 second timeout), as such, a new entry is created each time arpresolve() is called. Therefore the maximum attempts made is always 1. Consequently the error code returned to the application is always 0. 2. Set the expiration of each incomplete entry to a 20-second lifetime. 3. Return "incomplete" entries to the application. 4. The return error code was incorrect. Reviewed by: kmacy Approved by: re Notes: svn path=/stable/8/; revision=198298
