2017-08-06net: phy: add I2C mdio busRussell King
Add an I2C MDIO bus bridge library, to allow phylib to access PHYs which are connected to an I2C bus instead of the more conventional MDIO bus. Such PHYs can be found in SFP adapters and SFF modules. Since PHYs appear at I2C bus address 0x40..0x5f, and 0x50/0x51 are reserved for SFP EEPROMs/diagnostics, we must not allow the MDIO bus to access these I2C addresses.

2017-08-06net: phy: provide a hook for link up/link down eventsRussell King
Sometimes, we need to do additional work between the PHY coming up and marking the carrier present - for example, we may need to wait for the PHY to MAC link to finish negotiation. This changes phylib to provide a notification function pointer which avoids the built-in netif_carrier_on() and netif_carrier_off() functions. Standard ->adjust_link functionality is provided by hooking a helper into the new ->phy_link_change method.

phy-core phy_lookup_setting() provides useful functionality in ethtool code outside phylib. Move it to phy-core and allow it to be re-used (eg, in phylink) rather than duplicated elsewhere. Note that this supports the larger linkmode space. As we move the phy settings table, we also need to move the guts of phy_supported_speeds() as well.

2017-08-06Merge branch 'IP-cleanup-LSRR-option-processing'David S. Miller
Paolo Abeni says: ==================== IP: cleanup LSRR option processing The __ip_options_echo() function expect a valid dst entry in skb->dst; as result we sometimes need to preserve the dst entry for the whole IP RX path. The current usage of skb->dst looks more a relic from ancient past that a real functional constraint. This patchset tries to remove such usage, and than drops some hacks currently in place in the IP code to keep skb->dst around. __ip_options_echo() uses of skb->dst for two different purposes: retrieving the netns assicated with the skb, and modify the ingress packet LSRR address list. The first patch removes the code modifying the ingress packet, and the second one provides an explicit netns argument to __ip_options_echo(). The following patches cleanup the current code keeping arund skb->dst for __ip_options_echo's sake. Updating the __ip_options_echo() function has been previously discussed here: http://marc.info/?l=linux-netdev&m=150064533516348&w=2 ==================== Signed-off-by: David S.

__ip_options_echo() does not need anymore skb->dst, so we can avoid explicitly preserving it for its own sake.

2017-08-06ip/options: explicitly provide net ns to __ip_options_echo()Paolo Abeni
__ip_options_echo() uses the current network namespace, and currently retrives it via skb->dst->dev. This commit adds an explicit 'net' argument to __ip_options_echo() and update all the call sites to provide it, usually via a simpler sock_net(). After this change, __ip_options_echo() no more needs to access skb->dst and we can drop a couple of hack to preserve such info in the rx path.

2017-08-06IP: do not modify ingress packet IP option in ip_options_echo()Paolo Abeni
While computing the response option set for LSRR, ip_options_echo() also changes the ingress packet LSRR addresses list, setting the last one to the dst specific address for the ingress packet - via memset(start[ ... The only visible effect of such change - beyond possibly damaging shared/cloned skbs - is modifying the data carried by ICMP replies changing the header information for reported the ingress packet, which violates RFC1122 3.2.2.6. All the others call sites just ignore the ingress packet IP options after calling ip_options_echo() Note that the last element in the LSRR option address list for the reply packet will be properly set later in the ip output path via ip_options_build(). This buggy memset() predates git history and apparently was present into the initial ip_options_echo() implementation in linux 1.3.30 but still looks wrong. The removal of the fib_compute_spec_dst() call will help completely dropping the skb->dst usage by __ip_options_echo() with a later patch.

The latest change of compat_sys_sigpending in commit 8f13621abced ("sigpending(): move compat to native") has broken it in two ways. First, it tries to write 4 bytes more than userspace expects: sizeof(old_sigset_t) == sizeof(long) == 8 instead of sizeof(compat_old_sigset_t) == sizeof(u32) == 4. Second, on big endian architectures these bytes are being written in the wrong order. This bug was found by strace test suite.

2017-08-05ext4: inplace xattr block update fails to deduplicate blocksTahsin Erdogan
When an xattr block has a single reference, block is updated inplace and it is reinserted to the cache. Later, a cache lookup is performed to see whether an existing block has the same contents. This cache lookup will most of the time return the just inserted entry so deduplication is not achieved. Running the following test script will produce two xattr blocks which can be observed in "File ACL: " line of debugfs output: mke2fs -b 1024 -I 128 -F -O extent /dev/sdb 1G mount /dev/sdb /mnt/sdb touch /mnt/sdb/{x,y} setfattr -n user.1 -v aaa /mnt/sdb/x setfattr -n user.2 -v bbb /mnt/sdb/x setfattr -n user.1 -v aaa /mnt/sdb/y setfattr -n user.2 -v bbb /mnt/sdb/y debugfs -R 'stat x' /dev/sdb | cat debugfs -R 'stat y' /dev/sdb | cat This patch defers the reinsertion to the cache so that we can locate other blocks with the same contents.

2017-08-05ext4: fix warning about stack corruptionArnd Bergmann
After commit 62d1034f53e3 ("fortify: use WARN instead of BUG for now"), we get a warning about possible stack overflow from a memcpy that was not strictly bounded to the size of the local variable: inlined from 'ext4_mb_seq_groups_show' at fs/ext4/mballoc.c:2322:2: include/linux/string.h:309:9: error: '__builtin_memcpy': writing between 161 and 1116 bytes into a region of size 160 overflows the destination [-Werror=stringop-overflow=] We actually had a bug here that would have been found by the warning, but it was already fixed last year in commit 30a9d7afe70e ("ext4: fix stack memory corruption with 64k block size"). This replaces the fixed-length structure on the stack with a variable-length structure, using the correct upper bound that tells the compiler that everything is really fine here. I also change the loop count to check for the same upper bound for consistency, but the existing code is already correct here. Note that while clang won't allow certain kinds of variable-length arrays in structures, this particular instance is fine, as the array is at the end of the structure, and the size is strictly bounded.

2017-08-05ext4: fix dir_nlink behaviourAndreas Dilger
The dir_nlink feature has been enabled by default for new ext4 filesystems since e2fsprogs-1.41 in 2008, and was automatically enabled by the kernel for older ext4 filesystems since the dir_nlink feature was added with ext4 in kernel 2.6.28+ when the subdirectory count exceeded EXT4_LINK_MAX-1. Automatically adding the file system features such as dir_nlink is generally frowned upon, since it could cause the file system to not be mountable on older kernel, thus preventing the administrator from rolling back to an older kernel if necessary. In this case, the administrator might also want to disable the feature because glibc's fts_read() function does not correctly optimize directory traversal for directories that use st_nlinks field of 1 to indicate that the number of links in the directory are not tracked by the file system, and could fail to traverse the full directory hierarchy. Fortunately, in the past ten years very few users have complained about incomplete file system traversal by glibc's fts_read(). This commit also changes ext4_inc_count() to allow i_nlinks to reach the full EXT4_LINK_MAX links on the parent directory (including "." and "..") before changing i_links_count to be 1.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Arnd Bergmann: "This comes a bit later than I planned, and as a consequence is a larger than it should be. Most of the changes are devicetree fixes, across lots of platforms: Renesas, Samsung Exynos, Marvell EBU, TI OMAP, Rockchips, Amlogic Meson, Sigma Desings Tango, Allwinner SUNxi and TI Davinci. Also across many platforms, I applied an older series of simple randconfig build fixes. This includes making the CONFIG_MTD_XIP option compile again, which had been broken for many years and probably has not been missed, but it felt wrong to just remove it completely. The only other changes are: - We enable HWSPINLOCK in defconfig to get some Qualcomm boards to work out of the box. - A few regression fixes for Texas Instruments OMAP2+. - A boot regression fix for the Renesas regulator quirk. - A suspend/resume fix for Uniphier SoCs, fixing the resume of the system bus" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (43 commits) ARM: dts: tango4: Request RGMII RX and TX clock delays bus: uniphier-system-bus: set up registers when resuming ARM64: dts: marvell: armada-37xx: Fix the number of GPIO on south bridge ARM: shmobile: rcar-gen2: Fix deadlock in regulator quirk arm64: defconfig: enable missing HWSPINLOCK ARM: pxa: select both FB and FB_W100 for eseries ARM: ixp4xx: fix ioport_unmap definition ARM: ep93xx: use ARM_PATCH_PHYS_VIRT correctly ARM: mmp: mark usb_dma_mask as __maybe_unused ARM: omap2: mark unused functions as __maybe_unused ARM: omap1: avoid unused variable warning ARM: sirf: mark sirfsoc_init_late as __maybe_unused ARM: ixp4xx: use normal prototype for {read,write}s{b,w,l} ARM: omap1/ams-delta: warn about failed regulator enable ARM: rpc: rename RAM_SIZE macro ARM: w90x900: normalize clk API ARM: ep93xx: normalize clk API ARM: dts: sun8i: a83t: Switch to CCU device tree binding macros arm64: allwinner: sun50i-a64: Correct emac register size ARM: dts: sunxi: h3/h5: Correct emac register size ...

Jiri Pirko says: ==================== net: sched: summer cleanup part 1, mainly in exts area This patchset is one of the couple cleanup patchsets I have in queue. The motivation aside the obvious need to "make things nicer" is also to prepare for shared filter blocks introduction. That requires tp->q removal, and therefore removal of all tp->q users. Patch 1 is just some small thing I spotted on the way Patch 2 removes one user of tp->q, namely tcf_em_tree_change Patches 3-8 do preparations for exts->nr_actions removal Patches 9-10 do simple renames of functions in cls* Patches 11-19 remove unnecessary calls of tcf_exts_change helper The last patch changes tcf_exts_change to don't take lock Tested by tools/testing/selftests/tc-testing v1->v2: - removed conversion of action array to list as noted by Cong - added the past patch instead - small rebases of patches 11-19 ==================== Signed-off-by: David S.

tcf_exts_change is always called on newly created exts, which are not used on fastpath. Therefore, simple struct copy is enough. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
