* ZFS: add bookmark renamingAndriy Gapon2019-10-036-42/+237
| | | | | | | | | | | | | | | | | | | | | The feature is implemented as an extension of the existing ZFS_IOC_RENAME ioctl. Both the userland and the DSL interfaces support renaming only a single bookmark at a time. As of now, there is no ZCP interface to the new functionality. I am going to add it once the DSL interface passes a test of time. This change picks up support for zfs_ioc_namecheck_t::ENTITY_NAME that was added to ZoL as part of Redacted Send/Receive feature by Paul Dagnelie <pcd@delphix.com>. This is needed to allow a bookmark name in zc_name.

The sysctl passes the string excluding the NUL, so req->newlen equal to PATH_MAX is too long.

* Override the TLS model when building mips64 binaries and static librariesKyle Evans2019-10-022-0/+11
| | | | | | | | | | | | | | | | | | | | | GCC uses "dynamic" TLS models when -fpic or -fPIC is explicitly specified on the command line (which is only true for shared libraries). It uses "static" (or "exec") TLS models otherwise. In particular, GCC does _not_ use dynamic TLS models when PIC is implicitly enabled (which it is on MIPS), only if a PIC flag is explicitly provided. llvm uses "dynamic" TLS models if PIC is enabled either via a PIC flag or if it is implicily enabled (as on MIPS64). This means that llvm on MIPS64 always uses "dynamic" TLS models. However, dynamic TLS models do not work for static binaries and libraries as the __tls_get_addr function they invoke is only defined in rtld.

* libusb: LIBUSB_DEBUG environment variable override of libusb_set_debugKyle Evans2019-10-021-4/+19
| | | | | | | | | | | | | | | | | | | | | The debug level generally just controls verbosity of libusb for debugging libusb devices/usage. We allow the environment to set the debug level independent of the application, but the application will always override this if it explicitly sets the debug level. Changing the environment is easy, but patching the software to change the debug level isn't necessarily easy or possible. Further, there's this write-only debug_fixed variable that would seem to imply that the debug level should be fixed, but it isn't currently used. Change the logic to use strtol() so we can detect real 0 vs. conversion failure, then honor debug_fixed in libusb_set_debug.
