+algorithms, offering different speed/guarantees ratios.  It contains
+a @emph{wrapper} choosing the estimated best sequence of variants in
+order to provide a guaranteed output as fast as possible.  In the case
+of the wrapper, the succession of variants is oblivious to the user.
+
+It includes an implementation of the BKZ reduction algorithm,
+including the BKZ-2.0 improvements (extreme enumeration
+pruning, pre-processing of blocks, early termination).  Additionally,
+Slide reduction and self dual BKZ are supported.
+
+It also includes a floating-point implementation of the
+Kannan-Fincke-Pohst algorithm that finds a shortest non-zero lattice
+vector.  For the same task, the GaussSieve algorithm is also available
+in fplll.  Finally, it contains a variant of the enumeration algorithm
+that computes a lattice vector closest to a given vector belonging to

+are integer matrices, A nonsingular.
+@item Compute the right nullspace or kernel of an integer matrix.
+@item Certified linear system solving:
+compute a minimal denominator solution x to a system Ax=b, where b is an
+integer vector and A is an integer matrix with arbitrary shape and
+rank profile.
+@end itemize
+
+In addition, IML provides some low level routines for a variety of mod p
+matrix operations: computing the row-echelon form, determinant, rank
+profile, and inverse of a mod p matrix. These mod p routines are not
+general purpose; they require that p satisfy some preconditions based on
+the dimension of the input matrix (usually p should be prime and should be
+no more than about 20 bits long).")

+non-strict) with rational coefficients; some special classes of polyhedra
+shapes that offer interesting complexity/precision tradeoffs; and grids
+which represent regularly spaced points that satisfy a set of linear
+congruence relations.  The library also supports finite powersets and
+products of (any kind of) polyhedra and grids, a mixed integer linear
+programming problem solver using an exact-arithmetic version of the simplex
+algorithm, a parametric integer programming solver, and primitives for
+termination analysis via the automatic synthesis of linear ranking

+Subject: [PATCH] auth: Reject DBUS_COOKIE_SHA1 for users other than the server
+ owner
+
+The DBUS_COOKIE_SHA1 authentication mechanism aims to prove ownership
+of a shared home directory by having the server write a secret "cookie"
+into a .dbus-keyrings subdirectory of the desired identity's home
+directory with 0700 permissions, and having the client prove that it can
+read the cookie. This never actually worked for non-malicious clients in
+the case where server uid != client uid (unless the server and client
+both have privileges, such as Linux CAP_DAC_OVERRIDE or traditional
+Unix uid 0) because an unprivileged server would fail to write out the
+cookie, and an unprivileged client would be unable to read the resulting
+file owned by the server.
+
+Additionally, since dbus 1.7.10 we have checked that ~/.dbus-keyrings
+is owned by the uid of the server (a side-effect of a check added to
+harden our use of XDG_RUNTIME_DIR), further ruling out successful use
+by a non-malicious client with a uid differing from the server's.
+
+Joe Vennix of Apple Information Security discovered that the
+implementation of DBUS_COOKIE_SHA1 was susceptible to a symbolic link
+attack: a malicious client with write access to its own home directory
+could manipulate a ~/.dbus-keyrings symlink to cause the DBusServer to
+read and write in unintended locations. In the worst case this could
+result in the DBusServer reusing a cookie that is known to the
+malicious client, and treating that cookie as evidence that a subsequent
+client connection came from an attacker-chosen uid, allowing
+authentication bypass.
+
+This is mitigated by the fact that by default, the well-known system
+dbus-daemon (since 2003) and the well-known session dbus-daemon (in
+stable releases since dbus 1.10.0 in 2015) only accept the EXTERNAL
+authentication mechanism, and as a result will reject DBUS_COOKIE_SHA1
+at an early stage, before manipulating cookies. As a result, this
+vulnerability only applies to:
+
+* system or session dbus-daemons with non-standard configuration
+* third-party dbus-daemon invocations such as at-spi2-core (although
+  in practice at-spi2-core also only accepts EXTERNAL by default)
+* third-party uses of DBusServer such as the one in Upstart
+
+Avoiding symlink attacks in a portable way is difficult, because APIs
+like openat() and Linux /proc/self/fd are not universally available.
+However, because DBUS_COOKIE_SHA1 already doesn't work in practice for
+a non-matching uid, we can solve this vulnerability in an easier way
+without regressions, by rejecting it early (before looking at
+~/.dbus-keyrings) whenever the requested identity doesn't match the
+identity of the process hosting the DBusServer.

+Subject: [PATCH] Fixed bug when specifying a delay
+
+The division in the 'loop' calculation in perform() was returning floating point values
+after the migration to Python 3, rather than rounding down. Changed to floor division.
+
+I think the floating point values kept 'loop == 0' from ever being
+true and the variables inside that conditional were never initialized,
+causing the following error when a delay other than 1 was specified:
+
+You did not select any stats, using -cdngy by default.

+  "Extract all transitive sources for CARGO-INPUTS and CARGO-DEVELOPMENT-INPUTS
+along their 'cargo-inputs' edges.
+
+Cargo requires all transitive crate dependencies' sources to be available
+in its index, even if they are optional (this is so it can generate
+deterministic Cargo.lock files regardless of the target platform or enabled
+features). Thus we need all transitive crate dependencies for any cargo
+dev-dependencies, but this is only needed when building/testing a crate directly
+(i.e. we will never need transitive dev-dependencies for any dependency crates).
+
+Another complication arises due potential dependency cycles from Guix's
+perspective: Although cargo does not permit cyclic dependencies between crates,
+however, it permits cycles to occur via dev-dependencies. For example, if crate
+X depends on crate Y, crate Y's tests could pull in crate X to to verify
+everything builds properly (this is a rare scenario, but it it happens for
+example with the `proc-macro2` and `quote` crates). This is allowed by cargo
+because tests are built as a pseudo-crate which happens to depend on the
+X and Y crates, forming an acyclic graph.
+
+We can side step this problem by only considering regular cargo dependencies
+since they are guaranteed to not have cycles. We can further resolve any
+potential dev-dependency cycles by extracting package sources (which never have
+any dependencies and thus no cycles can exist).
+
+There are several implications of this decision:
+* Building a package definition does not require actually building/checking
+any dependent crates. This can be a benefits:
+ - For example, sometimes a crate may have an optional dependency on some OS
+ specific package which cannot be built or run on the current system. This
+ approach means that the build will not fail if cargo ends up internally ignoring
+ the dependency.
+ - It avoids waiting for quadratic builds from source: cargo always builds
+ dependencies within the current workspace. This is largely due to Rust not
+ having a stable ABI and other resolutions that cargo applies. This means that
+ if we have a depencency chain of X -> Y -> Z and we build each definition
+ independently the following will happen:
+  * Cargo will build and test crate Z
+  * Cargo will build crate Z in Y's workspace, then build and test Y
+  * Cargo will build crates Y and Z in X's workspace, then build and test X
+* But there are also some downsides with this approach:
+  - If a dependent crate is subtly broken on the system (i.e. it builds but its
+  tests fail) the consuming crates may build and test successfully but
+  actually fail during normal usage (however, the CI will still build all
+  packages which will give visibility in case packages suddenly break).
+  - Because crates aren't declared as regular inputs, other Guix facilities
+  such as tracking package graphs may not work by default (however, this is
+  something that can always be extended or reworked in the future)."
