It supports establishing passive open connection through firmware filter work request. Passive open connection will go through this path as now instead of listening server we create a server filter which will redirect the incoming SYN packet to the offload queue. It divides filter region into regular filters and server filter portion. It introduces new server filter region which will be exclusively used for creating server filters. This region will not overlap with regular filter region. It provides new API cxgb4_alloc_sftid in LLD for getting stid in case of LE hash collision path. This new stid will be used to open server filter in the filter region. Signed-off-by: NVipul Pandya <vipul@chelsio.com> Signed-off-by: NRoland Dreier <roland@purestorage.com>

The T4 architecture is capable of filtering ingress packets at line rate using the rule in TCAM. If packet hits a rule in the TCAM then it can be either dropped or passed to the receive queues based on a rule settings. This patch adds framework for managing filters and to use T4's filter capabilities. It constructs a Firmware Filter Work Request which writes the filter at a specified index to get the work done. It hosts shadow copy of ingress filter entry to check field size limitations and save memory in the case where the filter table is large.

Pull target updates from Nicholas Bellinger: "It has been a very busy development cycle this time around in target land, with the highlights including: - Kill struct se_subsystem_dev, in favor of direct se_device usage (hch) - Simplify reservations code by combining SPC-3 + SCSI-2 support for virtual backends only (hch) - Simplify ALUA code for virtual only backends, and remove left over abstractions (hch) - Pass sense_reason_t as return value for I/O submission path (hch) - Refactor MODE_SENSE emulation to allow for easier addition of new mode pages. (roland) - Add emulation of MODE_SELECT (roland) - Fix bug in handling of ExpStatSN wrap-around (steve) - Fix bug in TMR ABORT_TASK lookup in qla2xxx target (steve) - Add WRITE_SAME w/ UNMAP=0 support for IBLOCK backends (nab) - Convert ib_srpt to use modern target_submit_cmd caller + drop legacy ioctx->kref usage (nab) - Convert ib_srpt to use modern target_submit_tmr caller (nab) - Add link_magic for fabric allow_link destination target_items for symlinks within target_core_fabric_configfs.c code (nab) - Allocate pointers in instead of full structs for config_group->default_groups (sebastian) - Fix 32-bit highmem breakage for FILEIO (sebastian) All told, hch was able to shave off another ~1K LOC by killing the se_subsystem_dev abstraction, along with a number of PR + ALUA simplifications. Also, a nice patch by Roland is the refactoring of MODE_SENSE handling, along with the addition of initial MODE_SELECT emulation support for virtual backends. Sebastian found a long-standing issue wrt to allocation of full config_group instead of pointers for config_group->default_group[] setup in a number of areas, which ends up saving memory with big configurations. He also managed to fix another long-standing BUG wrt to broken 32-bit highmem support within the FILEIO backend driver.

This reverts commit 53b87cf0. It causes odd bootup problems on x86-64. Markus Trippelsdorf gets a repeatable oops, and I see a non-repeatable oops (or constant stream of messages that scroll off too quickly to read) that seems to go away with this commit reverted. So we don't know exactly what is wrong with the commit, but it's definitely problematic, and worth reverting sooner rather than later.

This reverts commit f269ae04. It turns out it causes a very noticeable interactivity regression with CONFIG_SCHED_AUTOGROUP (test-case: "make -j32" of the kernel in a terminal window, while scrolling in a browser - the autogrouping means that the two end up in separate cgroups, and the browser should be smooth as silk despite the high load). Says Paul Turner: "It seems that the update-throttling on the wake-side is reducing the interactive tasks' ability to preempt. While I suspect the right longer term answer here is force these updates only in the cross-cgroup case; this is less trivial. For this release I believe the right answer is either going to be a revert or restore the updates on the enqueue-side."

This reverts commit 1645bf1b. Brian Norris writes: > David Daney writes: > I can seem to find it. Without knowing what that does, I would be inclined > to NACK the whole thing. A NACK is probably the right thing. I was mostly converting a few other drivers which used some simple, common patterns to use my new common code, but this driver was missing it altogether. It looks like there may be bigger issues, though, as you point out. > This patch is likely to be incomplete as the driver is also missing the > module_exit() things. > > It might be simpler to just make the driver "bool" instead of "tristate" in > the Kconfig. As noted earlier, I don't have much interest in this driver. I agree that there are some other issues with the driver; I think it leaks memory if it is ever allowed to unload, for one. Feel free to submit an alternative patch to prevent this driver from being built as a module. Signed-off-by: NJeff Garzik <jgarzik@redhat.com>

Merge emailed autofs cleanup/fix patches from Ian Kent * autofs: autofs4 - use simple_empty() for empty directory check autofs4 - dont clear DCACHE_NEED_AUTOMOUNT on rootless mount
-
由 Ian Kent 提交于
For direct (and offset) mounts, if an automounted mount is manually umounted the trigger mount dentry can appear non-empty causing it to not trigger mounts. This can also happen if there is a file handle leak in a user space automounting application. This happens because, when a ioctl control file handle is opened on the mount, a cursor dentry is created which causes list_empty() to see the dentry as non-empty. Since there is a case where listing the directory of these dentrys is needed, the use of dcache_dir_*() functions for .open() and .release() is needed. Consequently simple_empty() must be used instead of list_empty() when checking for an empty directory.

The DCACHE_NEED_AUTOMOUNT flag is cleared on mount and set on expire for autofs rootless multi-mount dentrys to prevent unnecessary calls to ->d_automount(). Since DCACHE_MANAGE_TRANSIT is always set on autofs dentrys ->d_managed() is always called so the check can be done in ->d_manage() without the need to change the flag. This still avoids unnecessary calls to ->d_automount(), adds negligible overhead and eliminates a seriously ugly check in the expire code.
