* - >500 static DTrace probes for the linuxulatorAlexander Leidinger2012-05-052-0/+10
| | | | | | | | | | | | | | | | | | | | | - DTrace scripts to check for errors, performance, ... they serve mostly as examples of what you can do with the static probe;s with moderate load the scripts may be overwhelmed, excessive lock-tracing may influence program behavior (see the last design decission) Design decissions: - use "linuxulator" as the provider for the native bitsize; add the bitsize for the non-native emulation (e.g. "linuxuator32" on amd64) - Add probes only for locks which are acquired in one function and released in another function. Locks which are aquired and released in the same function should be easy to pair in the code, inter-function locking is more easy to verify in DTrace. - Probes for locks should be fired after locking and before releasing to prevent races (to provide data/function stability in DTrace, see the man-page of "dtrace -v ..." and the corresponding DTrace docs).

| | | | | | | | | | | | | | | | patch modifies makesyscalls.sh to prefix all of the non-compatibility calls (e.g. not linux_, freebsd32_) with sys_ and updates the kernel entry points and all places in the code that use them. It also fixes an additional name space collision between the kernel function psignal and the libc function of the same name by renaming the kernel psignal kern_psignal(). By introducing this change now we will ease future MFCs that change syscalls. Reviewed by: rwatson Approved by: re (bz) Notes: svn path=/head/; revision=225617
* Second-to-last commit implementing Capsicum capabilities in the FreeBSDRobert Watson2011-08-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | I have not properly thought through the commit. After r220031 (linux compat: improve and fix sendmsg/recvmsg compatibility) the basic handling for SO_PASSCRED is not sufficient as it breaks recvmsg functionality for SCM_CREDS messages because now we would need to handle sockcred data in addition to cmsgcred.
