…collide with the user's namespace. - Correct size and position variables type from long to size_t. - Do not set errno to ENOMEM on malloc failure, as malloc already does so. - Implement the concept of "buffer data length", which mandates what SEEK_END refers to and the allowed extent for a read. - Use NULL as read-callback if the buffer is opened in write-only mode. Conversely, use NULL as write-callback when opened in read-only mode. - Implement the handling of the ``b'' character in the mode argument. A binary buffer differs from a text buffer (default mode if ``b'' is omitted) in that NULL bytes are never appended to writes and that the "buffer data length" equals to the size of the buffer. - Remove shall from the man page. Use indicative instead. Also, specify that the ``b'' flag does not conform with POSIX but is supported by glibc. - Update the regression test so that the ``b'' functionality and the "buffer data length" concepts are tested. - Minor style(9) corrections.

Since ARP and routing are separated, "proxy only" entries don't have any meaning, thus we don't need additional field in sockaddr to pass SIN_PROXY flag. New kernel is binary compatible with old tools, since sizes of sockaddr_inarp and sockaddr_in match, and sa_family are filled with same value. The structure declaration is left for compatibility with third party software, but in tree code no longer use it. Reviewed by: ru, andre, net@
Right now, ic_curchan seems to be updated rather quickly (ie, during the ioctl) and before the driver gets notified of what's going on. So what I was seeing was: * NIC was in channel X; * It generates PHY errors for channel X; * an ioctl comes along from userland and changes things to channel Y; * .. this updates ic_curchan, but hasn't yet reset the hardware; * in parallel, RX is occuring and it looks at ic_curchan; * .. which is channel Y, so events get stamped with that now. Sigh.

This is also useful for out of the system compilation of the FreeBSD USB stack for various purposes. The USB kernel files can now optionally include a global header file which should include all needed definitions required to compile the FreeBSD USB stack. When the global USB header file is included, no other USB header files will be included by default. Add new file containing the USB stack configuration for the FreeBSD loader build. Replace some __FBSDID()'s by /* $FreeBSD$ */ comments. Now all USB files follow the same style.

… close their socket connection any time, and devd only notices that when it gets an error trying to write an event to the client. On a system with no device change activity, clients could connect and disappear repeatedly without devd noticing, leading to an ever-growing list of open socket descriptors in devd. Now devd uses poll(2) looking for POLLHUP on all existing clients every time a new client connection is established, and also periodically (once a minute) to proactively find zombie clients and reap the socket descriptors. It also now has a connection limit, configurable with a new -l <num> command line arg. When the maximum number of connections is reached it stops accepting new connections until some current clients drop off. Reviewed by: imp Approved by: cognet (mentor)

timecounter to 1, and correspondingly increase the precision of the gettimeofday(2) and related functions in the default configuration. The motivation for the TSC-low timecounter, as described in the r222866, seems to provide a workaround for the non-serializing behaviour of the RDTSC on some Intel hardware. Tests demonstrate that even with the pre-shift of 8, the cross-core non-monotonicity of the RDTSC is still observed reliably, e.g. on the Nehalems. The r238755 and r238973 implemented the proper fix for the issue. The pre-shift of 1 is applied to keep TSC not overflowing for the frequency of hardclock down to 2 sec/intr. The pre-shift is made a tunable to allow the easy debugging of the issues users could see with the shift being too low. Reviewed by: bde MFC after: 2 weeks
