==================== Changes in man-pages-3.37 ==================== Released: 2012-03-06, Christchurch Contributors ------------ The following people contributed patches/fixes or (noted in brackets in the changelog below) reports, notes and ideas that have been incorporated in changes in this release: Denys Vlasenko Denys Vlasenko Mark R. Bannister Michael Kerrisk Oleg Nesterov Tejun Heo Apologies if I missed anyone! New and rewritten pages ----------------------- getent.1 Mark R. Bannister New page to document 'getent' binary provided by glibc Changes to individual pages --------------------------- bdflush.2 Michael Kerrisk Note that bdflush() is deprecated, and does nothing nfsservctl.2 Michael Kerrisk Note that this system call was removed in Linux 3.1 ptrace.2 Denys Vlasenko [Oleg Nesterov, Tejun Heo] add extended description of various ptrace quirks Changes include: s/parent/tracer/g, s/child/tracee/g - ptrace interface now is sufficiently cleaned up to not treat tracing process as parent. Deleted several outright false statements: - pid 1 can be traced - tracer is not shown as parent in ps output - PTRACE_ATTACH is not "the same behavior as if tracee had done a PTRACE_TRACEME": PTRACE_ATTACH delivers a SIGSTOP. - SIGSTOP _can_ be injected. - Removed mentions of SunOS and Solaris as irrelevant. - Added a few more known bugs. Added a large block of text in DESCRIPTION which doesn't focus on mechanical description of each flag and operation, but rather tries to describe a bigger picture. The targeted audience is a person which is reasonably knowledgeable in Unix but did not spend years working with ptrace, and thus may be unaware of its quirks. This text went through several iterations of review by Oleg Nesterov and Tejun Heo. This block of text intentionally uses as little markup as possible, otherwise future modifications to it will be very hard to make. Michael Kerrisk Global clean-up of page * Wording and formatting fixes to existing text and Denys Vlasenko's new text. * Various technical amendments and improvements to Denys Vlasenko's new text. * Added FIXME for various problems with the current text.
