commit 13648b01 upstream. /proc/<pid>/maps currently don't annotate stack vma with "[stack]" This is because KSTK_ESP ie expected to return usermode SP of tsk while currently it returns the kernel mode SP of a sleeping tsk. While the fix is trivial, we also need to adjust the ARC kernel stack unwinder to not use KSTK_SP and friends any more. Reported-and-suggested-by:

commit 9c1c98a3 upstream. The current minstrel_ht rate control behavior is somewhat optimistic in trying to find optimum TX rate. While this is usually fine for normal Data frames, there are cases where a more conservative set of retry parameters would be beneficial to make the connection more robust. EAPOL frames are critical to the authentication and especially the EAPOL-Key message 4/4 (the last message in the 4-way handshake) is important to get through to the AP. If that message is lost, the only recovery mechanism in many cases is to reassociate with the AP and start from scratch. This can often be avoided by trying to send the frame with more conservative rate and/or with more link layer retries. In most cases, minstrel_ht is currently using the initial EAPOL-Key frames for probing higher rates and this results in only five link layer transmission attempts (one at high(ish) MCS and four at MCS0). While this works with most APs, it looks like there are some deployed APs that may have issues with the EAPOL frames using HT MCS immediately after association. Similarly, there may be issues in cases where the signal strength or radio environment is not good enough to be able to get frames through even at couple of MCS 0 tries. The best approach for this would likely to be to reduce the TX rate for the last rate (3rd rate parameter in the set) to a low basic rate (say, 6 Mbps on 5 GHz and 2 or 5.5 Mbps on 2.4 GHz), but doing that cleanly requires some more effort. For now, we can start with a simple one-liner that forces the minimum rate to be used for EAPOL frames similarly how the TX rate is selected for the IEEE 802.11 Management frames. This does result in a small extra latency added to the cases where the AP would be able to receive the higher rate, but taken into account how small number of EAPOL frames are used, this is likely to be insignificant. A future optimization in the minstrel_ht design can also allow this patch to be reverted to get back to the more optimized initial TX rate. It should also be noted that many drivers that do not use minstrel as the rate control algorithm are already doing similar workarounds by forcing the lowest TX rate to be used for EAPOL frames.

commit 7ed620bb upstream. While adding support loading kernel and initrd above 4G to grub2 in legacy mode, I was referring to efi_high_alloc(). That will allocate buffer for kernel and then initrd, and initrd will use kernel buffer start as limit. During testing found two buffers will be overlapped when initrd size is very big like 400M. It turns out efi_high_alloc() boundary checking is not right. end - size will be the new start, and should not compare new start with max, we need to make sure end is smaller than max. [ Basically, with the current efi_high_alloc() code it's possible to allocate memory above 'max', because efi_high_alloc() doesn't check that the tail of the allocation is below 'max'. If you have an EFI memory map with a single entry that looks like so, [0xc0000000-0xc0004000] And want to allocate 0x3000 bytes below 0xc0003000 the current code will allocate [0xc0001000-0xc0004000], not [0xc0000000-0xc0003000] like you would expect. - Matt ] Signed-off-by:

commit 1e7e4fb6 upstream. The commit 97374792 ("usb: host: xhci-plat: add support for the Armada 375/38x XHCI controllers") extended the xhci-plat driver to support the Armada 375/38x SoCs, mostly by adding a quirk configuring the MBUS window. However, that quirk was run before the clock the controllers needs has been enabled. This usually worked because the clock was first enabled by the bootloader, and left as such until the driver is probe, where it tries to access the MBUS configuration registers before enabling the clock. Things get messy when EPROBE_DEFER is involved during the probe, since as part of its error path, the driver will rightfully disable the clock. When the driver will be reprobed, it will retry to access the MBUS registers, but this time with the clock disabled, which hangs forever. Fix this by running the quirks after the clock has been enabled by the driver. Signed-off-by:

commit 4ff6f8e6 upstream. This has been broken for a long time: it broke first in 2.6.35, then was almost fixed in 2.6.36 but this one-liner slipped through the cracks. The bug shows up as an infinite loop in Windows 7 (and newer) boot on 32-bit hosts without EPT. Windows uses CMPXCHG8B to write to page tables, which causes a page fault if running without EPT; the emulator is then called from kvm_mmu_page_fault. The loop then happens if the higher 4 bytes are not 0; the common case for this is that the NX bit (bit 63) is 1. Fixes: 6550e1f1 Fixes: 16518d5aReported-by:

commit a0456399 upstream. The "Extended Compat ID OS Feature Descriptor Specification" does not require the (sub)compatible ids to be NUL-terminated, because they are placed in a fixed-size buffer and only unused parts of it should contain NULs. If the buffer is fully utilized, there is no place for NULs. Consequently, the code which uses desc->ext_compat_id never expects the data contained to be NUL terminated. If the compatible id is stored after sub-compatible id, and the compatible id is full length (8 bytes), the (useless) NUL terminator overwrites the first byte of the sub-compatible id. If the sub-compatible id is full length (8 bytes), the (useless) NUL terminator ends up out of the buffer. The situation can happen in the RNDIS function, where the buffer is a part of struct f_rndis_opts. The next member of struct f_rndis_opts is a mutex, so its first byte gets overwritten. The said byte is a part of a mutex'es member which contains the information on whether the muext is locked or not. This can lead to a deadlock, because, in a configfs-composed gadget when a function is linked into a configuration with config_usb_cfg_link(), usb_get_function() is called, which then calls rndis_alloc(), which tries locking the same mutex and (wrongly) finds it already locked. This patch eliminates NUL terminating of the (sub)compatible id. Fixes: da424314: "usb: gadget: configfs: OS Extended Compatibility descriptors support" Reported-by:

commit 89bb35e2 upstream. Using the touchscreen while running buffered capture results in the buffer reporting lots of wrong values, often just zeros. This is because we push readings to the buffer every time a touchscreen interrupt arrives, including when the buffer's own conversions have not yet finished. So let's only push to the buffer when its conversions are ready. Signed-off-by:

commit 6abe0300 upstream. Reading a channel through sysfs, or starting a buffered capture, can occasionally turn off the touchscreen. This is because the read_raw() and buffer preenable()/postdisable() callbacks unschedule current conversions on all channels. If a delay channel happens to schedule a touchscreen conversion at the same time, the conversion gets cancelled and the touchscreen sequence stops. This is probably related to this note from the reference manual: "If a delay group schedules channels to be sampled and a manual write to the schedule field in CTRL0 occurs while the block is discarding samples, the LRADC will switch to the new schedule and will not sample the channels that were previously scheduled. The time window for this to happen is very small and lasts only while the LRADC is discarding samples." So make the callbacks only unschedule conversions for the channels they use. This means channel 0 for read_raw() and channels 0-5 for the buffer (if the touchscreen is enabled). Since the touchscreen uses different channels (6 and 7), it no longer gets turned off. This is tested and fixes the issue on i.MX28, but hasn't been tested on i.MX23. Signed-off-by:

commit f81197b8 upstream. The touchscreen was initially designed [1] to map all of its physical channels to one virtual channel, leaving buffered capture to use the remaining 7 virtual channels. When the touchscreen was reimplemented [2], it was made to use four virtual channels, which overlap and conflict with the channels the buffer uses. As a result, when the buffer is enabled, the touchscreen's virtual channels are remapped to whichever physical channels the buffer was configured with, causing the touchscreen to read those instead of the touch measurement channels. Effectively the touchscreen stops working. So here we separate the channels again, giving the touchscreen 2 virtual channels and the buffer 6. We can't give the touchscreen just 1 channel as before, as the current pressure calculation requires 2 channels to be read at the same time. This makes the touchscreen continue to work during buffered capture. It has been tested on i.MX28, but not on i.MX23.

commit 957ed60b upstream. Each inode of nilfs2 stores a root node of a b-tree, and it turned out to have a memory overrun issue: Each b-tree node of nilfs2 stores a set of key-value pairs and the number of them (in "bn_nchildren" member of nilfs_btree_node struct), as well as a few other "bn_*" members. Since the value of "bn_nchildren" is used for operations on the key-values within the b-tree node, it can cause memory access overrun if a large number is incorrectly set to "bn_nchildren". For instance, nilfs_btree_node_lookup() function determines the range of binary search with it, and too large "bn_nchildren" leads nilfs_btree_node_get_key() in that function to overrun. As for intermediate b-tree nodes, this is prevented by a sanity check performed when each node is read from a drive, however, no sanity check has been done for root nodes stored in inodes. This patch fixes the issue by adding missing sanity check against b-tree root nodes so that it's called when on-memory inodes are read from ifile, inode metadata file. Signed-off-by:

commit 9d42d48a upstream. The native (64-bit) sigval_t union contains sival_int (32-bit) and sival_ptr (64-bit). When a compat application invokes a syscall that takes a sigval_t value (as part of a larger structure, e.g. compat_sys_mq_notify, compat_sys_timer_create), the compat_sigval_t union is converted to the native sigval_t with sival_int overlapping with either the least or the most significant half of sival_ptr, depending on endianness. When the corresponding signal is delivered to a compat application, on big endian the current (compat_uptr_t)sival_ptr cast always returns 0 since sival_int corresponds to the top part of sival_ptr. This patch fixes copy_siginfo_to_user32() so that sival_int is copied to the compat_siginfo_t structure. Reported-by:

commit d1901ef0 upstream. When a drive is marked write-mostly it should only be the target of reads if there is no other option. This behaviour was broken by commit 9dedf603 md/raid1: read balance chooses idlest disk for SSD which causes a write-mostly device to be *preferred* is some cases. Restore correct behaviour by checking and setting best_dist_disk and best_pending_disk rather than best_disk. We only need to test one of these as they are both changed from -1 or >=0 at the same time. As we leave min_pending and best_dist unchanged, any non-write-mostly device will appear better than the write-mostly device. Reported-by:

commit c2996cb2 upstream. The KSTK_EIP() and KSTK_ESP() macros should return the user program counter (PC) and stack pointer (A0StP) of the given task. These are used to determine which VMA corresponds to the user stack in /proc/<pid>/maps, and for the user PC & A0StP in /proc/<pid>/stat. However for Meta the PC & A0StP from the task's kernel context are used, resulting in broken output. For example in following /proc/<pid>/maps output, the 3afff000-3b021000 VMA should be described as the stack: # cat /proc/self/maps ... 100b0000-100b1000 rwxp 00000000 00:00 0 [heap] 3afff000-3b021000 rwxp 00000000 00:00 0 And in the following /proc/<pid>/stat output, the PC is in kernel code (1074234964 = 0x40078654) and the A0StP is in the kernel heap (1335981392 = 0x4fa17550): # cat /proc/self/stat 51 (cat) R ... 1335981392 1074234964 ... Fix the definitions of KSTK_EIP() and KSTK_ESP() to use task_pt_regs(tsk)->ctx rather than (tsk)->thread.kernel_context. This gets the registers from the user context stored after the thread info at the base of the kernel stack, which is from the last entry into the kernel from userland, regardless of where in the kernel the task may have been interrupted, which results in the following more correct /proc/<pid>/maps output: # cat /proc/self/maps ... 0800b000-08070000 r-xp 00000000 00:02 207 /lib/libuClibc-0.9.34-git.so ... 100b0000-100b1000 rwxp 00000000 00:00 0 [heap] 3afff000-3b021000 rwxp 00000000 00:00 0 [stack] And /proc/<pid>/stat now correctly reports the PC in libuClibc (134320308 = 0x80190b4) and the A0StP in the [stack] region (989864576 = 0x3b002280): # cat /proc/self/stat 51 (cat) R ... 989864576 134320308 ...

commit dfcc70a8 upstream. For filesystems without separate project quota inode field in the superblock we just reuse project quota file for group quotas (and vice versa) if project quota file is allocated and we need group quota file. When we reuse the file, quota structures on disk suddenly have wrong type stored in d_flags though. Nobody really cares about this (although structure type reported to userspace was wrong as well) except that after commit 14bf61ff (quota: Switch ->get_dqblk() and ->set_dqblk() to use bytes as space units) assertion in xfs_qm_scall_getquota() started to trigger on xfs/106 test (apparently I was testing without XFS_DEBUG so I didn't notice when submitting the above commit).
