sc_prohibit_internal_functions:
util: add VIR_(APPEND|INSERT|DELETE)_ELEMENT I noticed when writing the backend functions for virNetworkUpdate that I was repeating the same sequence of memmove, VIR_REALLOC, nXXX-- (and messed up the args to memmove at least once), and had seen the same sequence in a lot of other places, so I decided to write a few utility functions/macros - see the .h file for full documentation. The intent is to reduce the number of lines of code, but more importantly to eliminate the need to check the element size and element count arithmetic every time we need to do this (I *always* make at least one mistake.) VIR_INSERT_ELEMENT: insert one element at an arbitrary index within an array of objects. The size of each object is determined automatically by the macro using sizeof(*array). The new element's contents are copied into the inserted space, then the original copy of contents are 0'ed out (if everything else was successful). Compile-time assignment and size compatibility between the array and the new element is guaranteed (see explanation below [*]) VIR_INSERT_ELEMENT_COPY: identical to VIR_INSERT_ELEMENT, except that the original contents of newelem are not cleared to 0 (i.e. a copy is made). VIR_APPEND_ELEMENT: This is just a special case of VIR_INSERT_ELEMENT that "inserts" one past the current last element. VIR_APPEND_ELEMENT_COPY: identical to VIR_APPEND_ELEMENT, except that the original contents of newelem are not cleared to 0 (i.e. a copy is made). VIR_DELETE_ELEMENT: delete one element at an arbitrary index within an array of objects. It's assumed that the element being deleted is already saved elsewhere (or cleared, if that's what is appropriate). All five of these macros have an _INPLACE variant, which skips the memory re-allocation of the array, assuming that the caller has already done it (when inserting) or will do it later (when deleting). Note that VIR_DELETE_ELEMENT* can return a failure, but only if an invalid index is given (index + amount to delete is > current array size), so in most cases you can safely ignore the return (that's why the helper function virDeleteElementsN isn't declared with ATTRIBUTE_RETURN_CHECK). A warning is logged if this ever happens, since it is surely a coding error. [*] One initial problem with the INSERT and APPEND macros was that, due to both the array pointer and newelem pointer being cast to void* when passing to virInsertElementsN(), any chance of type-checking was lost. If we were going to move in newelem with a memmove anyway, we would be no worse off for this. However, most current open-coded insert/append operations use direct struct assignment to move the new element into place (or just populate the new element directly) - thus use of the new macros would open a possibility for new usage errors that didn't exist before (e.g. accidentally sending &newelemptr rather than newelemptr - I actually did this quite a lot in my test conversions of existing code). But thanks to Eric Blake's clever thinking, I was able to modify the INSERT and APPEND macros so that they *do* check for both assignment and size compatibility of *ptr (an element in the array) and newelem (the element being copied into the new position of the array). This is done via clever use of the C89-guaranteed fact that the sizeof() operator must have *no* side effects (so an assignment inside sizeof() is checked for validity, but not actually evaluated), and the fact that virInsertElementsN has a "# of new elements" argument that we want to always be 1.

Document bracket whitespace rules & add syntax-check rule This documents the following whitespace rules if(foo) // Bad if (foo) // Good int foo (int wizz) // Bad int foo(int wizz) // Good bar = foo (wizz); // Bad bar = foo(wizz); // Good typedef int (*foo) (int wizz); // Bad typedef int (*foo)(int wizz); // Good int foo( int wizz ); // Bad int foo(int wizz); // Good There is a syntax-check rule extension to validate all these rules.

It must also ignore source comments and quoted strings. It is not possible todo this with a simple regex in the normal syntax-check style. So a short Perl script is created instead to analyse the source. In practice this works well enough. The only thing it can't cope with is multi-line quoted strings of the form "start of string\ more lines\ more line\ the end" but this can and should be written as "start of string" "more lines" "more line" "the end" with this simple change, the bracket checking script does not have any false positives across libvirt source, provided it is only run against .c files. It is not practical to run it against .h files, since those use whitespace extensively to get alignment (though this is somewhat inconsistent and could arguably be fixed). The only limitation is that it cannot detect a violation where the first arg starts with a '*', eg foo(*wizz); since this generates too many false positives on function typedefs which can't be supressed efficiently.

Stop linking tests/commandhelper to libvirt code The commandhelper binary is a helper for commandtest that validates what file handles were inherited. For this to work reliably we must not have any libraries that leak file descriptors into commandhelper. Unfortunately some versions of gnutls will intentionally open file handles at library load time via a constructor function. We previously hacked around this in commit 4cbc15d037e1cd8abf5c4aa6acc30d83ae13e34d Author: Martin Kletzander <mkletzan@redhat.com> Date: Fri May 2 09:55:52 2014 +0200 tests: don't fail with newer gnutls gnutls-3.3.0 and newer leaves 2 FDs open in order to be backwards compatible when it comes to chrooted binaries [1]. Linking commandhelper with gnutls then leaves these two FDs open and commandtest fails thanks to that. This patch does not link commandhelper with libvirt.la, but rather only the utilities making the test pass. Based on suggestion from Daniel [2]. [1] http://lists.gnutls.org/pipermail/gnutls-help/2014-April/003429.html [2] https://www.redhat.com/archives/libvir-list/2014-April/msg01119.html That fix relied on fact that while libvirt.so linked with gnutls, libvirt_util.la did not link to it. With the introduction of the util/vircrypto.c file that assumption is no longer valid. We must not link to libvirt_util.la at all - only gnulib and libc can (hopefully) be relied on not to open random file descriptors in constructors.

Stop linking tests/commandhelper to libvirt code The commandhelper binary is a helper for commandtest that validates what file handles were inherited. For this to work reliably we must not have any libraries that leak file descriptors into commandhelper. Unfortunately some versions of gnutls will intentionally open file handles at library load time via a constructor function. We previously hacked around this in commit 4cbc15d037e1cd8abf5c4aa6acc30d83ae13e34d Author: Martin Kletzander <mkletzan@redhat.com> Date: Fri May 2 09:55:52 2014 +0200 tests: don't fail with newer gnutls gnutls-3.3.0 and newer leaves 2 FDs open in order to be backwards compatible when it comes to chrooted binaries [1]. Linking commandhelper with gnutls then leaves these two FDs open and commandtest fails thanks to that. This patch does not link commandhelper with libvirt.la, but rather only the utilities making the test pass. Based on suggestion from Daniel [2]. [1] http://lists.gnutls.org/pipermail/gnutls-help/2014-April/003429.html [2] https://www.redhat.com/archives/libvir-list/2014-April/msg01119.html That fix relied on fact that while libvirt.so linked with gnutls, libvirt_util.la did not link to it. With the introduction of the util/vircrypto.c file that assumption is no longer valid. We must not link to libvirt_util.la at all - only gnulib and libc can (hopefully) be relied on not to open random file descriptors in constructors.

Rewrite all the DTrace/SystemTAP probing The libvirtd daemon had a few crude system tap probes. Some of these were broken during the RPC rewrite. The new modular RPC code is structured in a way that allows much more effective tracing. Instead of trying to hook up the original probes, define a new set of probes for the RPC and event code. The master probes file is now src/probes.d. This contains probes for virNetServerClientPtr, virNetClientPtr, virSocketPtr virNetTLSContextPtr and virNetTLSSessionPtr modules. Also add probes for the poll event loop. The src/dtrace2systemtap.pl script can convert the probes.d file into a libvirt_probes.stp file to make use from systemtap much simpler. The src/rpc/gensystemtap.pl script can generate a set of systemtap functions for translating RPC enum values into printable strings. This works for all RPC header enums (program, type, status, procedure) and also the authentication enum The PROBE macro will automatically generate a VIR_DEBUG statement, so any place with a PROBE can remove any existing manual DEBUG statements. * daemon/libvirtd.stp, daemon/probes.d: Remove obsolete probing * daemon/libvirtd.h: Remove probe macros * daemon/Makefile.am: Remove all probe buildings/install * daemon/remote.c: Update authentication probes * src/dtrace2systemtap.pl, src/rpc/gensystemtap.pl: Scripts to generate STP files * src/internal.h: Add probe macros * src/probes.d: Master list of probes * src/rpc/virnetclient.c, src/rpc/virnetserverclient.c, src/rpc/virnetsocket.c, src/rpc/virnettlscontext.c, src/util/event_poll.c: Insert probe points, removing any DEBUG statements that duplicate the info

Add some autoconf helper macros for checking for libraries Most checks for libraries take the same format * --with-libFOO=yes|no|check|/some/path argument * check for a function NNN in libFOO.so * check for a header file DDD/HHH.h * Define a WITH_FOO config.h symbol * Define a WITH_FOO make conditional * Substitute FOO_CFLAGS and FOO_LIBS make variables * Print CFLAGS & LIBS summary at the end Doing all this correctly is rather difficult, typically done by copy+paste of a previous usage. Further small improvements people make are not applied to all previous usages. Improve this by creating some helper macros to apply good practice. First, to perform the actual checks: LIBVIRT_CHECK_LIB([SELINUX], [selinux], [getfilecon], [selinux/selinux.h]) This checks for 'getfilecon' in -lselinux, and the existence of 'selinux/selinux.h' header file. If successful it sets SELINUX_CFLAGS and SELINUX_LIBS. The WITH_SELINUX config.h macro and WITH_SELINUX make conditional are also defined. In some cases we need to check two variants of the same library LIBVIRT_CHECK_LIB_ALT([SASL], [sasl2], [sasl_client_init], [sasl/sasl.h], [SASL1], [sasl], [sasl_client_init], [sasl/sasl.h]) This checks for sasl_client_init in libsasl2, and if that is not found, checks sasl_client_init in libsasl. If the first check succeeds WITH_SASL is set, while if the second check succeeds *both* WITH_SASL and WITH_SASL1 are set. If the library supports pkg-config, then another variant is available LIBVIRT_CHECK_PKG([AVAHI], [avahi-client], [0.6.0]) This checks for avahi-client >= 0.6.0 via pkg-config and sets WITH_AVAHI if found. Finally to print a summary of CFLAGS & LIBs found (if any): LIBVIRT_RESULT_LIB([SELINUX]) Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
