2008-12-08sparse irq_desc[] array: core kernel and x86 changesYinghai Lu
Impact: new feature Problem on distro kernels: irq_desc[NR_IRQS] takes megabytes of RAM with NR_CPUS set to large values. The goal is to be able to scale up to much larger NR_IRQS value without impacting the (important) common case. To solve this, we generalize irq_desc[NR_IRQS] to an (optional) array of irq_desc pointers. When CONFIG_SPARSE_IRQ=y is used, we use kzalloc_node to get irq_desc, this also makes the IRQ descriptors NUMA-local (to the site that calls request_irq()). This gets rid of the irq_cfg[] static array on x86 as well: irq_cfg now uses desc->chip_data for x86 to store irq_cfg.

2007-02-12[PATCH] mark struct file_operations const 1Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2006-10-17[PATCH] rename net_random to random32Stephen Hemminger
Make net_random() more widely available by calling it random32 akpm: hopefully this will permit the removal of carta_random32. That needs confirmation from Stephane - this code looks somewhat more computationally expensive, and has a different (ie: callee-stateful) interface.

2005-03-04[PATCH] Randomisation: infrastructureArjan van de Ven
The patch below introduces get_random_int() and randomize_range(), two helpers used in later patches in the series. get_random_int() shares the tcp/ip random number stuff so the CONFIG_INET ifdef needs to move slightly, and to reduce the damange due to that, secure_ip_id() needs to move inside random.c From: Frank Sorenson <frank@tuxrocks.com> Acked-By: Jeff Dike <jdike@addtoit.com> The stack randomization patches that went into 2.6.11-rc3-mm1 broke compilation of ARCH=um. This patch fixes compiling by adding arch_align_stack back in.

2005-02-08[IPV6]: match TCP port selection behavior with ipv4Stephen Hemminger
This patch makes TCP over IPV6 select ports the same way the current TCPv4 code does. It uses a hash function to provide a starting offset and a free running counter to provide seed. This changes the port selection semantics to match TCPv4 as well. If the port is in use but to a different remote address, it will get reused. It looks like the TCPv6 code was not updated when the TCPv4 code changed. Now the code in ipv4/tcp_ipv4.c and ipv6/tcp_ipv6.c are almost identical for tcp_hash_connect.

2005-01-14[PATCH] random: add_input_randomnessMatt Mackall
The input layer wants to send us an entropy event per input event and who are we to argue? Create add_input_randomness with an input-friendly interface and kill the remaining two keyboard and mouse sources. This eliminates lots of duplicate entropy events while covering all the input bases nicely. We now get two events per keystroke as we should, one down and one up.

2004-12-19[TCP]: Efficient port randomization (rev 3)Stephen Hemminger
okay, here is the revised version. Testing shows that it is more consistent, and just as fast as existing code, probably because of the getting rid of portalloc_lock and better distribution. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
