Pero elsync_rcu() agregado a la funci\u00f3n swap la ralentiza innecesariamente: se puede mover con seguridad para destruir y usar call_rcu() en su lugar. Eric Dumazet se\u00f1al\u00f3 que simplemente llamar a las funciones de destrucci\u00f3n como devoluci\u00f3n de llamada de rcu no funciona: los conjuntos con tiempo de espera usan recolectores de basura que necesitan cancelarse en la destrucci\u00f3n y que pueden esperar. Por lo tanto, las funciones de destrucci\u00f3n se dividen en dos: cancelar los recolectores de basura de forma segura al ejecutar el comando recibido por netlink y mover la parte restante solo a la devoluci\u00f3n de llamada de rcu.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\",\"baseScore\":4.7,\"baseSeverity\":\"MEDIUM\"},\"exploitabilityScore\":1.0,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-362\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"5.4.269\",\"matchCriteriaId\":\"48E561A5-2F59-4E74-BFAB-39B8D844FD15\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.5\",\"versionEndExcluding\":\"5.10.210\",\"matchCriteriaId\":\"F5CB4CA6-A9A0-4AFD-9102-8CF94D708170\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.11\",\"versionEndExcluding\":\"5.15.149\",\"matchCriteriaId\":\"0D0465BB-4053-4E15-9137-6696EBAE90FD\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.16\",\"versionEndExcluding\":\"6.1.79\",\"matchCriteriaId\":\"656E2F29-1779-4EFC-AA64-8F984E2885B1\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.2\",\"versionEndExcluding\":\"6.6.18\",\"matchCriteriaId\":\"BD961E49-FEDA-47CF-BF23-4D2BD942B4E0\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.7\",\"versionEndExcluding\":\"6.7.6\",\"matchCriteriaId\":\"C6D6A5C8-7308-42A9-8A72-ABF3DEA4BB82\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/653bc5e6d9995d7d5f497c665b321875a626161c\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/970709a67696b100a57b33af1a3d75fc34b747eb\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/97f7cf1cd80eeed3b7c808b7c12463295c751001\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/a24d5f2ac8ef702a58e55ec276aad29b4bd97e05\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/b93a6756a01f4fd2f329a39216f9824c56a66397\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/c2dc077d8f722a1c73a24e674f925602ee5ece49\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/c7f2733e5011bfd136f1ca93497394d43aa76225\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]}]}}"
