Commit b2029520 ("perf, core: Rate limit perf_sched_events jump_label patching") introduced rate limiting for jump label disabling. The changes were made in the jump label code in order to be more widely available and to keep things tidier. This is all fine, except now jump_label.h includes linux/workqueue.h, which makes it impossible to include jump_label.h from anything that workqueue.h needs. For example, it's now impossible to include jump_label.h from asm/spinlock.h, which is done in proposed pv-ticketlock patches. This patch splits out the rate limiting related changes from jump_label.h into a new file, jump_label_ratelimit.h, to resolve the issue. Signed-off-by:

Increment ticket head/tails by 2 rather than 1 to leave the LSB free to store a "is in slowpath state" bit. This halves the number of possible CPUs for a given ticket size, but this shouldn't matter in practice - kernels built for 32k+ CPU systems are probably specially built for the hardware rather than a generic distro kernel.

Although the lock_spinning calls in the spinlock code are on the uncommon path, their presence can cause the compiler to generate many more register save/restores in the function pre/postamble, which is in the fast path. To avoid this, convert it to using the pvops callee-save calling convention, which defers all the save/restores until the actual function is called, keeping the fastpath clean. Signed-off-by:

Replace the old Xen implementation of PV spinlocks with and implementation of xen_lock_spinning and xen_unlock_kick. xen_lock_spinning simply registers the cpu in its entry in lock_waiting, adds itself to the waiting_cpus set, and blocks on an event channel until the channel becomes pending. xen_unlock_kick searches the cpus in waiting_cpus looking for the one which next wants this lock with the next ticket, if any. If found, it kicks it by making its event channel pending, which wakes it up. We need to make sure interrupts are disabled while we're relying on the contents of the per-cpu lock_waiting values, otherwise an interrupt handler could come in, try to take some other lock, block, and overwrite our values.

The code size expands somewhat, and its better to just call a function rather than inline it. Thanks Jeremy for original version of ARCH_NOINLINE_SPIN_UNLOCK config patch, which is simplified. Suggested-by:

Rather than outright replacing the entire spinlock implementation in order to paravirtualize it, keep the ticket lock implementation but add a couple of pvops hooks on the slow patch (long spin on lock, unlocking a contended lock). Ticket locks have a number of nice properties, but they also have some surprising behaviours in virtual environments. They enforce a strict FIFO ordering on cpus trying to take a lock; however, if the hypervisor scheduler does not schedule the cpus in the correct order, the system can waste a huge amount of time spinning until the next cpu can take the lock. (See Thomas Friebel's talk "Prevent Guests from Spinning Around" http://www.xen.org/files/xensummitboston08/LHP.pdf for more details.) To address this, we add two hooks: - __ticket_spin_lock which is called after the cpu has been spinning on the lock for a significant number of iterations but has failed to take the lock (presumably because the cpu holding the lock has been descheduled). The lock_spinning pvop is expected to block the cpu until it has been kicked by the current lock holder. - __ticket_spin_unlock, which on releasing a contended lock (there are more cpus with tail tickets), it looks to see if the next cpu is blocked and wakes it if so. When compiled with CONFIG_PARAVIRT_SPINLOCKS disabled, a set of stub functions causes all the extra code to go away.

NetLabel has the ability to selectively assign network security labels to outbound traffic based on either the LSM's "domain" (different for each LSM), the network destination, or a combination of both. Depending on the type of traffic, local or forwarded, and the type of traffic selector, domain or address based, different hooks are used to label the traffic; the goal being minimal overhead. Unfortunately, there is a bug such that a system using NetLabel domain based traffic selectors does not correctly label outbound local traffic that is not assigned to a socket. The issue is that in these cases the associated NetLabel hook only looks at the address based selectors and not the domain based selectors. This patch corrects this by checking both the domain and address based selectors so that the correct labeling is applied, regardless of the configuration type. In order to acomplish this fix, this patch also simplifies some of the NetLabel domainhash structures to use a more common outbound traffic mapping type: struct netlbl_dommap_def. This simplifies some of the code in this patch and paves the way for further simplifications in the future. Signed-off-by:

It's possible to assign an invalid value to the net.core.somaxconn sysctl variable, because there is no checks at all. The sk_max_ack_backlog field of the sock structure is defined as unsigned short. Therefore, the backlog argument in inet_listen() shouldn't exceed USHRT_MAX. The backlog argument in the listen() syscall is truncated to the somaxconn value. So, the somaxconn value shouldn't exceed 65535 (USHRT_MAX). Also, negative values of somaxconn are meaningless. before: $ sysctl -w net.core.somaxconn=256 net.core.somaxconn = 256 $ sysctl -w net.core.somaxconn=65536 net.core.somaxconn = 65536 $ sysctl -w net.core.somaxconn=-100 net.core.somaxconn = -100 after: $ sysctl -w net.core.somaxconn=256 net.core.somaxconn = 256 $ sysctl -w net.core.somaxconn=65536 error: "Invalid argument" setting key "net.core.somaxconn" $ sysctl -w net.core.somaxconn=-100 error: "Invalid argument" setting key "net.core.somaxconn" Based on a prior patch from Changli Gao.
