* kernel: fix crashlog on x86/64Jo-Philipp Wich2016-08-151-2/+6
| | | | | | | | | | | | The bootmem area reserved for crashlog might be smaller than CRASHLOG_OFFSET bytes, leading to an integer underflow when calculating the memory address in crashlog_set_addr() which subsequently causes the kernel to crash when attempting to vmap() the crashlog pages. Change the logic to only consider the offset when the size of the used memory area is sufficient. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
* kernel: backport upstream challenge ACK fix (CVE-2016-5696)Jo-Philipp Wich2016-08-133-0/+218
| | | | | | | | | | | | Yue Cao claims that current host rate limiting of challenge ACKS (RFC 5961) could leak enough information to allow a patient attacker to hijack TCP sessions. He will soon provide details in an academic paper. Backports upstream commit 75ff39ccc1bd5d3c455b6822ab09e533c551f758 to the used LEDE kernel versions. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

* b53: allow ports with higher numbers than CPU portRafał Miłecki2016-07-241-2/+1
| | | | | | | | | | | | | | Our code was assuming CPU port uses the highest number. My BCM53573 device has eth0 connected to port 8 and eth1 connected to port 5. While working on support for it I tried to: 1) Enable all ports (including port 8) 2) Set CPU port to 5 I noticed port 8 is not accessible anymore. It was just a development process but it seems like something worth fixing anyway. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Acked-by: Jonas Gorski <jonas.gorski@gmail.com>
* linux: Get rid of 000-keep_initrafs_the_default.patchAlexey Brodkin2016-07-233-75/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With that patch in place for initramfs no additional options are reported for "/" partition. What's really important is missing info about sizes. Which in its turn makes opkg think that there's no space on "/" partition to install software. I understand that's a sort of corner-case, people rarely install packages on ramfs but anyways why not? Just in case that's what I see with the patch: ---------------------->8-------------------- root@lede:/# cat /proc/mounts rootfs / rootfs rw 0 0 proc /proc proc rw,nosuid,nodev,noexec,noatime 0 0 sysfs /sys sysfs rw,nosuid,nodev,noexec,noatime 0 0 tmpfs /tmp tmpfs rw,nosuid,nodev,noatime 0 0 tmpfs /dev tmpfs rw,nosuid,relatime,size=512k,mode=755 0 0 devpts /dev/pts devpts rw,nosuid,noexec,relatime,mode=600 0 0 debugfs /sys/kernel/debug debugfs rw,noatime 0 0 ---------------------->8-------------------- And without: ---------------------->8-------------------- root@lede:/# cat /proc/mounts rootfs / rootfs rw,size=256168k,nr_inodes=32021 0 0 proc /proc proc rw,nosuid,nodev,noexec,noatime 0 0 sysfs /sys sysfs rw,nosuid,nodev,noexec,noatime 0 0 tmpfs /tmp tmpfs rw,nosuid,nodev,noatime 0 0 tmpfs /dev tmpfs rw,nosuid,relatime,size=512k,mode=755 0 0 devpts /dev/pts devpts rw,nosuid,noexec,relatime,mode=600 0 0 debugfs /sys/kernel/debug debugfs rw,noatime 0 0 ---------------------->8-------------------- Note how different is entry for rootfs. And given there's no known rationale for that patch we're getting rid of it.

* kernel: Fix ipv6 mc snooping if bridge has no ipv6 addressdaniel2016-06-301-0/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a backport for current LEDE 4.4 Kernels. It is already upstream, for linux-next and stable. The initial commit message is below: The bridge is falsly dropping ipv6 mulitcast packets if there is: 1. No ipv6 address assigned on the brigde. 2. No external mld querier present. 3. The internal querier enabled. When the bridge fails to build mld queries, because it has no ipv6 address, it slilently returns, but keeps the local querier enabled. This specific case causes confusing packet loss. Ipv6 multicast snooping can only work if: a) An external querier is present OR b) The bridge has an ipv6 address an is capable of sending own queries Otherwise it has to forward/flood the ipv6 multicast traffic, because snooping cannot work. This patch fixes the issue by adding a flag to the bridge struct that indicates that there is currently no ipv6 address assinged to the bridge and returns a false state for the local querier in __br_multicast_querier_exists().

* kernel: remove full cache flush in fuse_copy_do() for MIPSHauke Mehrtens2016-06-263-96/+0
| | | | | | | | | | | | | | | | | | | | | | | | This patch was introduced in commit r16412 for the brcm47xx target only and then moved to generic in commit r32395. It was initially added because of ticket #5186 and should fix some problems with fuse file systems and MIPS caches. The commit comment in r32395 says that this a generic problem in MIPS CPUs, but does not name any specifics about that. There was a fix added to kernel 2.6.21 in commit commit 7575a49f20 "[MIPS] Implement flush_anon_page()." that should fix this problem, but that was already available before both commits were done to OpenWrt. I just tested fuse with ntfs.3g without this patch on a BCM4704 (BMIPS3300 V0.6) SoC and haven't seen any problems. Someone reported that removing this patch improves some fuse operations by 5 times on some modern MIPS cores. My test was only a simple "dd if=/dev/zero of=/mnt/zero bs=5000" to an USB stick. This patch removes the patch to OpenWrt, because I assume that it is not needed any more and Felix, the orginal author, also thinks so. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

Place the members which are already in upstream header at the same position as in that kernel and add our own at the end. The kernel should not have a problem when there are some additional members and just ignore them. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
