* [IPV6]: Generalise tcp_v6_search_req & tcp_v6_synq_addArnaldo Carvalho de Melo2006-01-035-73/+137
| | | | | | | | | More work is needed tho to introduce inet6_request_sock from tcp6_request_sock, in the same layout considerations as ipv6_pinfo in inet_sock, next changeset will do that.

* [IPV4]: Safer reassemblyHerbert Xu2006-01-038-1/+106
| | | | | | | | | | | | | | | | | Another spin of Herbert Xu's "safer ip reassembly" patch for 2.6.16. (The original patch is here: http://marc.theaimsgroup.com/?l=linux-netdev&m=112281936522415&w=2 and my only contribution is to have tested it.) This patch (optionally) does additional checks before accepting IP fragments, which can greatly reduce the possibility of reassembling fragments which originated from different IP datagrams.

* [NETFILTER] ip_tables: NUMA-aware allocationEric Dumazet2006-01-033-182/+382
| | | | | | | | | | | | | | | | | Part of a performance problem with ip_tables is that memory allocation is not NUMA aware, but 'only' SMP aware (ie each CPU normally touch separate cache lines) Even with small iptables rules, the cost of this misplacement can be high on common workloads. Instead of using one vmalloc() area (located in the node of the iptables process), we now allocate an area for each possible CPU, using vmalloc_node() so that memory should be allocated in the CPU's node if possible.

* [LSM-IPSec]: Per-packet access control.Trent Jaeger2006-01-036-0/+410
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch series implements per packet access control via the extension of the Linux Security Modules (LSM) interface by hooks in the XFRM and pfkey subsystems that leverage IPSec security associations to label packets. Extensions to the SELinux LSM are included that leverage the patch for this purpose. This patch implements the changes necessary to the SELinux LSM to create, deallocate, and use security contexts for policies (xfrm_policy) and security associations (xfrm_state) that enable control of a socket's ability to send and receive packets. Patch purpose: The patch is designed to enable the SELinux LSM to implement access control on individual packets based on the strongly authenticated IPSec security association. Such access controls augment the existing ones in SELinux based on network interface and IP address. The former are very coarse-grained, and the latter can be spoofed. By using IPSec, the SELinux can control access to remote hosts based on cryptographic keys generated using the IPSec mechanism. This enables access control on a per-machine basis or per-application if the remote machine is running the same mechanism and trusted to enforce the access control policy. Patch design approach: The patch's main function is to authorize a socket's access to a IPSec policy based on their security contexts. Since the communication is implemented by a security association, the patch ensures that the security association's negotiated and used have the same security context. The patch enables allocation and deallocation of such security contexts for policies and security associations. It also enables copying of the security context when policies are cloned. Lastly, the patch ensures that packets that are sent without using a IPSec security assocation with a security context are allowed to be sent in that manner. A presentation available at www.selinux-symposium.org/2005/presentations/session2/2-3-jaeger.pdf from the SELinux symposium describes the overall approach. Patch implementation details: The function which authorizes a socket to perform a requested operation (send/receive) on a IPSec policy (xfrm_policy) is selinux_xfrm_policy_lookup. The Netfilter and rcv_skb hooks ensure that if a IPSec SA with a securit y association has not been used, then the socket is allowed to send or receive the packet, respectively. The patch implements SELinux function for allocating security contexts when policies (xfrm_policy) are created via the pfkey or xfrm_user interfaces via selinux_xfrm_policy_alloc. When a security association is built, SELinux allocates the security context designated by the XFRM subsystem which is based on that of the authorized policy via selinux_xfrm_state_alloc. When a xfrm_policy is cloned, the security context of that policy, if any, is copied to the clone via selinux_xfrm_policy_clone. When a xfrm_policy or xfrm_state is freed, its security context, if any is also freed at selinux_xfrm_policy_free or selinux_xfrm_state_free. Testing: The SELinux authorization function is tested using ipsec-tools. We created policies and security associations with particular security contexts and added SELinux access control policy entries to verify the authorization decision. We also made sure that packets for which no security context was supplied (which either did or did not use security associations) were authorized using an unlabelled context.

* [LSM-IPSec]: Security association restriction.Trent Jaeger2006-01-0312-61/+655
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch series implements per packet access control via the extension of the Linux Security Modules (LSM) interface by hooks in the XFRM and pfkey subsystems that leverage IPSec security associations to label packets. Extensions to the SELinux LSM are included that leverage the patch for this purpose. This patch implements the changes necessary to the XFRM subsystem, pfkey interface, ipv4/ipv6, and xfrm_user interface to restrict a socket to use only authorized security associations (or no security association) to send/receive network packets. Patch purpose: The patch is designed to enable access control per packets based on the strongly authenticated IPSec security association. Such access controls augment the existing ones based on network interface and IP address. The former are very coarse-grained, and the latter can be spoofed. By using IPSec, the system can control access to remote hosts based on cryptographic keys generated using the IPSec mechanism. This enables access control on a per-machine basis or per-application if the remote machine is running the same mechanism and trusted to enforce the access control policy. Patch design approach: The overall approach is that policy (xfrm_policy) entries set by user-level programs (e.g., setkey for ipsec-tools) are extended with a security context that is used at policy selection time in the XFRM subsystem to restrict the sockets that can send/receive packets via security associations (xfrm_states) that are built from those policies. A presentation available at www.selinux-symposium.org/2005/presentations/session2/2-3-jaeger.pdf from the SELinux symposium describes the overall approach. Patch implementation details: On output, the policy retrieved (via xfrm_policy_lookup or xfrm_sk_policy_lookup) must be authorized for the security context of the socket and the same security context is required for resultant security association (retrieved or negotiated via racoon in ipsec-tools). This is enforced in xfrm_state_find. On input, the policy retrieved must also be authorized for the socket (at __xfrm_policy_check), and the security context of the policy must also match the security association being used. The patch has virtually no impact on packets that do not use IPSec. The existing Netfilter (outgoing) and LSM rcv_skb hooks are used as before. Also, if IPSec is used without security contexts, the impact is minimal. The LSM must allow such policies to be selected for the combination of socket and remote machine, but subsequent IPSec processing proceeds as in the original case. Testing: The pfkey interface is tested using the ipsec-tools. ipsec-tools have been modified (a separate ipsec-tools patch is available for version 0.5) that supports assignment of xfrm_policy entries and security associations with security contexts via setkey and the negotiation using the security contexts via racoon. The xfrm_user interface is tested via ad hoc programs that set security contexts. These programs are also available from me, and contain programs for setting, getting, and deleting policy for testing this interface. Testing of sa functions was done by tracing kernel behavior.

* [PATCH] Avoid namespace pollution in <asm/param.h>Dag-Erling Smørgrav2006-01-022-4/+2
| | | | | | | | | | | | | | | | In commit 3D59121003721a8fad11ee72e646fd9d3076b5679c, the x86 and x86-64 <asm/param.h> was changed to include <linux/config.h> for the configurable timer frequency. However, asm/param.h is sometimes used in userland (it is included indirectly from <sys/param.h>), so your commit pollutes the userland namespace with tons of CONFIG_FOO macros. This greatly confuses software packages (such as BusyBox) which use CONFIG_FOO macros themselves to control the inclusion of optional features.

* [PATCH] powerpc: more g5 overtemp problem fixBenjamin Herrenschmidt2006-01-021-3/+3
| | | | | | | | | | | | | | | | | Some G5s still occasionally experience shutdowns due to overtemp conditions despite the recent fix. After analyzing logs from such machines, it appears that the overtemp code is a bit too quick at shutting the machine down when reaching the critical temperature (tmax + 8) and doesn't leave the fan enough time to actually cool it down. This happens if the temperature of a CPU suddenly rises too high in a very short period of time, or occasionally on boot (that is the CPUs are already overtemp by the time the driver loads). This patches makes the code a bit more relaxed, leaving a few seconds to the fans to do their job before kicking the machine shutown.

* | [PATCH] Fix false old value return of sysctlYi Yang2005-12-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the sysctl syscall, if the user wants to get the old value of a sysctl entry and set a new value for it in the same syscall, the old value is always overwritten by the new value if the sysctl entry is of string type and if the user sets its strategy to sysctl_string. This issue lies in the strategy being run twice if the strategy is set to sysctl_string, the general strategy sysctl_string always returns 0 if success. Such strategy routines as sysctl_jiffies and sysctl_jiffies_ms return 1 because they do read and write for the sysctl entry. The strategy routine sysctl_string return 0 although it actually read and write the sysctl entry. According to my analysis, if a strategy routine do read and write, it should return 1, if it just does some necessary check but not read and write, it should return 0, for example sysctl_intvec.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were passing set_capacity() the capacity we calculated in terms of the number of blocks on the card, which happened to be the right units for 512-byte block cards. However, with 1024-byte block cards, we end up setting the capacity to half the number of blocks. Fix this by shifting by the appropriate amount. Thanks to Todd Blumer for pointing this out. Use get_capacity() to report the card capacity, rather than recalculating it from the CSD information. Finally, use our chosen IO block size for the SET_BLOCKLEN command rather than the CSD read block size. Currently these are equivalent, but will not be in the future.

Until when we switch to running on init_stack, current_thread_info() evaluates to crap. Printk uses "current" at times (in detail, &current is evaluated with CONFIG_DEBUG_SPINLOCK to check the spinlock owner task). And this leads to random segmentation faults. Exactly, what happens is that &current = *(current_thread_info()), i.e. round down $esp and dereference the value. I.e. access the stack below $esp, which causes SIGSEGV on a VM_GROWSDOWN vma (see arch/i386/mm/fault.c).

Problem remains fixed. Prevent tg3_get_regs() from reading reserved and undocumented registers at RX_CPU_BASE and TX_CPU_BASE offsets which caused hostile behavior on PCIe platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Noticed by Christophe Zimmerman, this explains the slow mouse movement with 2.6.x kernels. And checking the 2.4.x drivers/sbus/char/sunmouse.c driver shows we always used a 5-byte protocol with Sun mice in the past. I have no idea how the 3-byte thing got into the 2.6.x driver, but it's surely wrong. Signed-off-by: David S. Miller <davem@davemloft.net>

* | | [PATCH] Fix more radeon GART start calculation casesBenjamin Herrenschmidt2005-12-271-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by Jules Villard <jvillard@ens-lyon.fr> and some others, the recent GART aperture start reconfiguration causes problems on some setups. What I _think_ might be happening is that the X server is also trying to muck around with the card memory map and is forcing it back into a wrong setting that also happens to no longer match what the DRM wants to do and blows up. There are bugs all over the place in that code (and still some bugs in the DRM as well anyway). This patch attempts to avoid that by using the largest of the 2 values, which I think will cause it to behave as it used to for you and will still fix the problem with machines that have an aperture size smaller than the video memory.

This is an obvious DOS path, requiring the host to store and then multicast as many sources as are queried (e.g., millions...). This alternative sends a full, relevant report that's limited to number of sources present on the machine. 4) fix "add_grec()" to send empty-source records when it should The original check doesn't account for a non-empty source list with all sources inactive; the new code keeps that short-circuit case, and also generates the group header with an empty list if needed. 5) fix mca_crcount decrement to be after add_grec(), which needs its original value These issues (other than item #1 ;-) ) were all found by Yan Zheng, much thanks!
