2013-11-21ACPI / sysfs: Fix incorrect ACPI tables walk in acpi_tables_sysfs_init()Jeremy Compostella
When executing on an ACPI Hardware Reduced hardware, all the ACPI tables are not exposed in sysfs due to the fact that FACS is silently ignored by the kernel in the ACPI hardware reduced mode and, moreover, the acpi_tables_sysfs_init() ACPI table walk is buggy and stops too soon. The acpi_tables_sysfs_init() function should rely on the acpi_status return value from acpi_get_table_by_index() to decide whether or not to stop the iteration (the walk should only be terminated when that value is AE_BAD_PARAMETER). This way, when running in an ACPI Harware Reduced environment (where the FACS table is silently ignored by the kernel) or if some ACPI tables are not correctly memory mapped or have bad checksums, it will still walk through the remaining tables that may be correct.

2013-11-21ACPI / sysfs: Set file size for each exposed ACPI tableDaisuke HATAYAMA
Currently, each of the ACPI tables exported from /sys/firmware/acpi/tables is of zero size: $ LANG=C ls -ld /sys/firmware/acpi/tables/* -r-------- 1 root root 0 Nov 19 09:48 /sys/firmware/acpi/tables/APIC -r-------- 1 root root 0 Nov 19 09:48 /sys/firmware/acpi/tables/BOOT -r-------- 1 root root 0 Nov 19 14:25 /sys/firmware/acpi/tables/DSDT -r-------- 1 root root 0 Nov 19 14:25 /sys/firmware/acpi/tables/FACP -r-------- 1 root root 0 Nov 19 14:25 /sys/firmware/acpi/tables/FACS -r-------- 1 root root 0 Nov 19 14:25 /sys/firmware/acpi/tables/MCFG -r-------- 1 root root 0 Nov 19 14:25 /sys/firmware/acpi/tables/SRAT drwxr-xr-x 2 root root 0 Nov 19 09:48 /sys/firmware/acpi/tables/dynamic/ due to which, user-land tools fail reading each table. For example: $ acpidump -f /sys/firmware/acpi/tables/SRAT Could not get input file size: /sys/firmware/acpi/tables/SRAT To deal with the issue, this patch assigns size of each ACPI table to the corresponding sysfs file. $ LANG=C ls -hld /sys/firmware/acpi/tables/* -r-------- 1 root root 94 Nov 19 16:45 /sys/firmware/acpi/tables/APIC -r-------- 1 root root 40 Nov 19 16:45 /sys/firmware/acpi/tables/BOOT -r-------- 1 root root 58K Nov 19 16:55 /sys/firmware/acpi/tables/DSDT -r-------- 1 root root 244 Nov 19 16:55 /sys/firmware/acpi/tables/FACP -r-------- 1 root root 64 Nov 19 16:55 /sys/firmware/acpi/tables/FACS -r-------- 1 root root 60 Nov 19 16:55 /sys/firmware/acpi/tables/MCFG -r-------- 1 root root 168 Nov 19 16:45 /sys/firmware/acpi/tables/SRAT drwxr-xr-x 2 root root 0 Nov 19 16:55 /sys/firmware/acpi/tables/dynamic/ Then, user-land tools work well like: $ acpidump -f /sys/firmware/acpi/tables/SRAT SRAT @ 0x0000000000000000 0000: 53 52 41 54 A8 00 00 00 02 65 56 4D 57 41 52 45 SRAT.....eVMWARE 0010: 4D 45 4D 50 4C 55 47 20 00 00 04 06 56 4D 57 20 MEMPLUG ....VMW 0020: 01 00 00 00 01 00 00 00 00 00 00 00 00 00 00 00 ................ 0030: 01 28 00 00 00 00 00 00 00 00 00 00 00 00 00 00 .(.............. 0040: 00 00 0A 00 00 00 00 00 00 00 00 00 01 00 00 00 ................ 0050: 00 00 00 00 00 00 00 00 01 28 00 00 00 00 00 00 .........(...... 0060: 00 00 10 00 00 00 00 00 00 00 F0 BF 00 00 00 00 ................ 0070: 00 00 00 00 01 00 00 00 00 00 00 00 00 00 00 00 ................ 0080: 01 28 00 00 00 00 00 00 00 00 00 00 01 00 00 00 .(.............. 0090: 00 00 00 40 00 00 00 00 00 00 00 00 01 00 00 00 ...@............ 00A0: 00 00 00 00 00 00 00 00 ........

2013-11-21KVM: kvm_clear_guest_page(): fix empty_zero_page usageHeiko Carstens
Using the address of 'empty_zero_page' as source address in order to clear a page is wrong. On some architectures empty_zero_page is only the pointer to the struct page of the empty_zero_page. Therefore the clear page operation would copy the contents of a couple of struct pages instead of clearing a page. For kvm only arm/arm64 are affected by this bug. To fix this use the ZERO_PAGE macro instead which will return the struct page address of the empty_zero_page on all architectures.

2013-11-20net: rework recvmsg handler msg_name and msg_namelen logicHannes Frederic Sowa
This patch now always passes msg->msg_namelen as 0. recvmsg handlers must set msg_namelen to the proper size <= sizeof(struct sockaddr_storage) to return msg_name to the user. This prevents numerous uninitialized memory leaks we had in the recvmsg handlers and makes it harder for new code to accidentally leak uninitialized memory. Optimize for the case recvfrom is called with NULL as address. We don't need to copy the address at all, so set it to NULL before invoking the recvmsg handler. We can do so, because all the recvmsg handlers must cope with the case a plain read() is called on them. read() also sets msg_name to NULL. Also document these changes in include/linux/net.h as suggested by David Miller. Changes since RFC: Set msg->msg_name = NULL if user specified a NULL in msg_name but had a non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't affect sendto as it would bail out earlier while trying to copy-in the address. It also more naturally reflects the logic by the callers of verify_iovec. With this change in place I could remove " if (!uaddr || msg_sys->msg_namelen == 0) msg->msg_name = NULL ". This change does not alter the user visible error logic as we ignore msg_namelen as long as msg_name is NULL. Also remove two unnecessary curly brackets in ___sys_recvmsg and change comments to netdev style.

2013-11-20btrfs: fix bio_size_ok() for max_sectors > 0xffffAkinobu Mita
The data type of max_sectors in queue settings is unsigned int. But this value is stored to the local variable whose type is unsigned short in bio_size_ok(). This can cause unexpected result when max_sectors > 0xffff.

2013-11-20btrfs: Use trace condition for get_extent tracepointSteven Rostedt
Doing an if statement to test some condition to know if we should trigger a tracepoint is pointless when tracing is disabled. This just adds overhead and wastes a branch prediction. This is why the TRACE_EVENT_CONDITION() was created. It places the check inside the jump label so that the branch does not happen unless tracing is enabled. That is, instead of doing: if (em) trace_btrfs_get_extent(root, em); Which is basically this: if (em) if (static_key(trace_btrfs_get_extent)) { Using a TRACE_EVENT_CONDITION() we can just do: trace_btrfs_get_extent(root, em); And the condition trace event will do: if (static_key(trace_btrfs_get_extent)) { if (em) { ... The static key is a non conditional jump (or nop) that is faster than having to check if em is NULL or not.

Commit b02441999efcc6152b87cd58e7970bb7843f76cf "Btrfs: don't wait for the completion of all the ordered extents" introduced a bug that broke the ordered root list: WARNING: CPU: 1 PID: 7119 at lib/list_debug.c:59 __list_del_entry+0x5a/0x98() It is because we forgot to return the roots in the splice list to the ordered list of the fs.

2013-11-20Btrfs: print bytenr instead of page pointer in check-intStefan Behrens
The page pointer information was useless. The bytenr is what you want when you search for submitted write bios. Additionally, a new bit in the print mask is added that allows to selectively enable the check-int submit_bio verbose mode. Before, the global verbose mode had to be enabled leading to many million useless lines in the kernel log. And a comment is added that explains that LOG_BUF_SHIFT needs to be set to a really high value.
