* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271982-159/+4089
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255
* rw: fix runlock_hard when new readers show upMateusz Guzik2017-11-261-0/+5
| | | | | | | | | | | | | When waiters/writer spinner flags are set no new readers can show up unless they already have a different rw rock read locked. The change in r326195 failed to take that into account - in presence of new readers it would spin until they all drain, which would be lead to trouble if e.g. they go off cpu and can get scheduled because of this thread.

* Synchronize TLB1 mappings when createdJustin Hibbits2017-11-261-18/+47
| | | | | | | | | | | This allows modules creating mappings to be loaded post-boot, after SMP has started. Without this, the TLB1 mappings can become unsynchronized and lead to kernel page faults when accessed on the alternate CPUs. MFC after: 3 weeks Notes: svn path=/head/; revision=326236

* Add to ipfw support for sending an SCTP packet containing an ABORT chunk.Michael Tuexen2017-11-263-5/+269
| | | | | | | | | | | | | | | | This is similar to the TCP case. where a TCP RST segment can be sent. There is one limitation: When sending an ABORT in response to an incoming packet, it should be tested if there is no ABORT chunk in the received packet. Currently, it is only checked if the first chunk is an ABORT chunk to avoid parsing the whole packet, which could result in a DOS attack. Thanks to Timo Voelker for helping me to test this patch.

* Add a Saved Process Status Register bit for AArch32 execution mode.Ed Schouten2017-11-262-3/+3
| | | | | | | | | | | | | | | | | | The documentation on the Saved Process Status Register (SPSR) is a bit weird; the M[4] bit is documented separately from M[3:0]. The M[4] bit can be toggled to switch to 32-bit execution mode. This functionality is orthogonal to M[3:0]. Change the definition of PSR_M_MASK to no longer include M[4]. Add a new definition, PSR_AARCH32 that can be used to toggle 32-bit independently. This bit will be used by the cloudabi32 code to force execution of userspace code in 32-bit mode.

| | | | | | | | | | | | | | The nice thing about ARM64 is that it's pretty elegant to install separate trap/exception handlers for 32-bit and 64-bit processes. That said, for all other architectures (e.g., i386 on amd64) we always let 32-bit counterparts go through the regular system call codepath. Let's do the same on ARM64.

* Decode kevent structures logged via ktrace(2) in kdump.John Baldwin2017-11-256-80/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add a new KTR_STRUCT_ARRAY ktrace record type which dumps an array of structures. The structure name in the record payload is preceded by a size_t containing the size of the individual structures. Use this to replace the previous code that dumped the kevent arrays dumped for kevent(). kdump is now able to decode the kevent structures rather than dumping their contents via a hexdump. One change from before is that the 'changes' and 'events' arrays are not marked with separate 'read' and 'write' annotations in kdump output. Instead, the first array is the 'changes' array, and the second array (only present if kevent doesn't fail with an error) is the 'events' array. For kevent(), empty arrays are denoted by an entry with an array containing zero entries rather than no record. - Move kevent decoding tables from truss to libsysdecode. This adds three new functions to decode members of struct kevent: sysdecode_kevent_filter, sysdecode_kevent_flags, and sysdecode_kevent_fflags. kdump uses these helper functions to pretty-print kevent fields. - Move structure definitions for freebsd11 and freebsd32 kevent structures to <sys/event.h> so that they can be shared with userland. The 32-bit structures are only exposed if _WANT_KEVENT32 is defined. The freebsd11 structures are only exposed if _WANT_FREEBSD11_KEVENT is defined. The 32-bit freebsd11 structure requires both. - Decode freebsd11 kevent structures in truss for the compat11.kevent() system call. - Log 32-bit kevent structures via ktrace for 32-bit compat kevent() system calls. - While here, constify the 'void *data' argument to ktrstruct().
