efi-boot-shim-debian/15+1533136590.3beb971-1.zip
* New upstream release.debian/15+1533136590.3beb971-1
- debian/patches/second-stage-path: dropped; the default loader path now includes an arch suffix. - debian/patches/sbsigntool-no-pesign: dropped; no longer needed. * Drop remaining patches that were not being applied. * Sync packaging from Ubuntu: - debian/copyright: Update upstream source location. - debian/control: add a Build-Depends on libelf-dev. - Enable arm64 build. - debian/patches/fixup_git.patch: don't run git in clean; we're not really in a git tree. - debian/rules, debian/shim.install: use the upstream install target as intended, and move files to the target directory using dh_install. - define RELEASE and COMMIT_ID for the snapshot. - Set ENABLE_HTTPBOOT to enable the HTTP Boot feature. - Update dh_auto_build/dh_auto_clean/dh_auto_install for new upstream options: set MAKELEVEL. - Define an EFI_ARCH variable, and use that for paths to shim. This makes it possible to build a shim for other architectures than amd64. - Set EFIDIR=$distro for dh_auto_install; that will let files be installed in the "right" final directories, and makes boot.csv for us. - Set ENABLE_SHIM_CERT, to keep using ephemeral self-signed certs built at compile-time for MokManager and fallback. - Set ENABLE_SBSIGN, to use sbsign instead of pesign for signing fallback and MokManager.

+ * This module supplies three routines:
+ *

+ * will actually query "bytes" bytes of entropy form the egd-socket located
+ * at path and will write them to buf (if supplied) or will directly feed
+ * it to RAND_seed() if buf==NULL.
+ * The number of bytes is not limited by the maximum chunk size of EGD,
+ * which is 255 bytes. If more than 255 bytes are wanted, several chunks
+ * of entropy bytes are requested. The connection is left open until the
+ * query is competed.
+ * RAND_query_egd_bytes() returns with
+ * -1 if an error occurred during connection or communication.
+ * num the number of bytes read from the EGD socket. This number is either
+ * the number of bytes requested or smaller, if the EGD pool is
+ * drained and the daemon signals that the pool is empty.
+ * This routine does not touch any RAND_status(). This is necessary, since
+ * PRNG functions may call it during initialization.
+ *
+ * RAND_egd_bytes(path, bytes) will query "bytes" bytes and have them
+ * used to seed the PRNG.
+ * RAND_egd_bytes() is a wrapper for RAND_query_egd_bytes() with buf=NULL.
+ * Unlike RAND_query_egd_bytes(), RAND_status() is used to test the
+ * seed status so that the return value can reflect the seed state:
+ * -1 if an error occurred during connection or communication _or_
+ * if the PRNG has still not received the required seeding.
+ * num the number of bytes read from the EGD socket. This number is either
+ * the number of bytes requested or smaller, if the EGD pool is
+ * drained and the daemon signals that the pool is empty.
+ *
+ * RAND_egd(path) will query 255 bytes and use the bytes retrieved to seed
+ * the PRNG.
