Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs. This means that their use is restricted to a single C file.

MFC: r227309 (partial)

Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs. The SYSCTL_NODE macro defines a list that stores all child-elements of that node. If there's no SYSCTL_DECL macro anywhere else, there's no reason why it shouldn't be static.

- Re-shuffle the headers to move all kernel-specific bits under #ifdef _KERNEL but leave definitions for various structures defined by standards ($PIR table, SMAP entries, etc.) available to userland. - Consolidate duplicate SMBIOS table structure definitions in ipmi(4) and smbios(4) in and make them available to userland.

Don't try to stop the IPMI watchdog timer if it is not running. Starting or stopping the IPMI watchdog is rather expensive with the current implementation as all IPMI requests are bounced via thread. This is not viable during shutdown or dumps, and this avoids headache in the common case that the watchdog is not enabled. The IPMI watchdog should probably be reworked to not use a separate thread to fix this in the case when the watchdog timer is enabled.

Second-to-last commit implementing Capsicum capabilities in the FreeBSD

2011-08-11T12:30:23Z

kernel for FreeBSD 9.0: Add a new capability mask argument to fget(9) and friends, allowing system call code to declare what capabilities are required when an integer file descriptor is converted into an in-kernel struct file *. With options CAPABILITIES compiled into the kernel, this enforces capability protection; without, this change is effectively a no-op. Some cases require special handling, such as mmap(2), which must preserve information about the maximum rights at the time of mapping in the memory map so that they can later be enforced in mprotect(2) -- this is done by narrowing the rights in the existing max_protection field used for similar purposes with file permissions. In namei(9), we assert that the code is not reached from within capability mode, as we're not yet ready to enforce namespace capabilities there. This will follow in a later commit. Update two capability names: CAP_EVENT and CAP_KEVENT become CAP_POST_KEVENT and CAP_POLL_KEVENT to more accurately indicate what they represent.

Rework the SMBIOS table walker to make it operate like other table walkers

and remove a buffer overflow: - Remove the array of per-type dispatch functions. Instead, pass each structure to a single callback. The callback should check the type of each table entry to take appropriate action. This matches the behavior of other table walkers such as for the MP Table and MADT. - Don't attempt to save an array of string pointers for each structure entry. Instead, just skip the strings. If this code is reused to provide a generic SMBIOS table walker in the future we could provide a method that looks up a specific string N for a given structure record instead of pre-populating an array of pointers. This fixes a buffer overflow for structure entries with more than 20 strings. PR: kern/148546 Reported by: Spencer Minear @ McAfee MFC after: 3 days

- Fixed incorrect watchdog timeout setting: MSB of a 2-byte

value is obtained by dividing it by 256, not by 2550; also, one second is 10^9 nanoseconds, not 1800000000 nanoseconds. - Due to rounding error, setting watchdog to a really small timeout (<1 sec) was turning the watchdog off. It should set the watchdog to a small timeout instead. - Implemented error checking in ipmi_wd_event(), as required by watchdog(9). PR: kern/130512 Submitted by: Dmitrij Tejblum - Additionally, check that the timeout value is within the supported range, and if it's too large, act as required by watchdog(9). MFC after: 3 days
